I finally fixed my calculator after my calc was stuck on stats plots. You helped a lot and I thank you. Ready to Ace my Pre-Calc class because of you!

[@pinkjade444]

Thank you so much! I need this calculator for my pre-calc course and now I finally know how to use it.

[@KermMartian]

Happy to help! Feel free to post if you have any questions, or certainly more helpfully, grab a copy of "Using the TI-84 Plus". :)

[@buddingnaturalist]

This is awesome, thanks so much for putting it up. Google led me to this video after a 'how do graph x=4 on the ti-84 plus CE' search.

[@thebabenarixx]

thank you so much! with covid there’s only so much my teacher could help me with through a zoom call, your videos are the best!

[@KermMartian]

Thanks! Do post here or on Cemetech if you get stuck on anything.

[@Emerald23928]

They should really teach people how to use this stuff in school, because that's when you get a graphing calculator and really the main time you need one

[@itzpayday1238]

Thank you so much! Just got my first graphing calculator, ti-84 plus ce and you just saved me a lot of time!

[@KermMartian]

I'm glad to hear it! Feel free to post questions here or on Cemetech.

[@streamedlined]

Your Videos are very helpful, I've got the exact red calculator. I'm trying to figure out how to graph an inequality

[@KermMartian]

+Joey Dollar Thank you, and good luck. You can use the graphing styles accessed at the far left of the Y= menu by moving the cursor all the way to the left from Y1 (or any other Y= equation), and pressing enter. You can shade below the graph for =, etc.

[@theelephant4680]

Same exact situation

[@simplesimon031]

Thanks SOOOOOOO much! I just started AP Calculus and i needed to use a calculator without knowing how. This saved me!

[@izzykwoka2379]

When I try to graph 2 equations on the same graph, an error message pops up saying TRANSFORMATUON GRAPHING Only 1 function and up to 3 plots will graph. Press GRAPH. However, my 2 functions are perfectly normal functions like the ones you put on the example and I have no idea what I'm doing wrong

[@rinnace]

did you ever figure out what was wrong? LOL, i know this was 2 years ago but i'm so confused

[@genie8970]

@@rinnacesame problem here 1 year later🥲

[@andreivolkov1]

Using Ti-84 Plus C Silver Edition: I entered the 3 equations on Y= screen and graphed them all at once, then entered Transformations Graphing app. Pressed Graph button - it graphed only one line as expected. Then I quit Transformation Graphing (double-checked that it is not running). Pressing Graph still plots only one of the 3 equations. Then I "edit" the second equation by replacing X with X. Pressing Graph now plots only 2 equations. Then I "edit" the third equation by replacing X with X. Pressing Graph now plots all 3 equations! Now, I start and quit Transformation again. Only one graph plots again. I add one more equation. Now only two equations plot - the first and the one I just entered! After I "edit" the remaining equations one after another (replacing X with X) they plot as well - as soon as the equation was "edited" its plot appears on Graph. Therefore, starting and quitting Transformation Graphing app somehow leaves the calculator in undesirable state that requires user to manually "edit" or "re-enter" all the equations except one before they can be plotted. This appears to be a bug - either in the operating system or in the Transformation Graphing app. Does it behave the same on TI-84 Plus CE?

[@KermMartian]

+My Run TV They probably stay deselected after Transformation Graphing ran. Did you try moving the cursor to the = symbol between Y1 (or Y2 or Y3) and the equation, and hitting [ENTER] to make sure it's white on a black background? When they weren't graphing, was the equals sign black on white or white on black? You can disable and enable equations by toggling that.

[@MrOzzz-fn3eb]

it tells me invalid dimension when I graphed x on y and x^2 on y^2

[@KermMartian]

+Amazing Gamer Keep watching further into the video where it explains what to do if this happens.

[@anvvii]

So when I’m graphing a function I don’t see a line graphed onto the line. I cleared my ram. Still doesn’t work. I typeed in y= 2/5x+20. It doesn’t show up. No line.

[@t2lacademy614]

Hi! I think you might have a problem with the minimums and maximums of the graph. The default only goes from x=-10 to x=10 on the x axis, and y=-10 to y=10 on the y axis. You would need to click "Window" on your calculator, and change the "Xmin", "Xmax", "Ymin", and "Ymax" values. Let me know if this helps!

[@Luis-rc4pq]

start at 8:09 if graphing x doesn't work for you

[@AndrewGulickTrueVitalityPlus]

after I went to Y= and confirmed that I was in function mode, entered the X to have Y=X and hit graph, I got the blue slanting line. You hit trace and got a flashing curser, but when I hit trace, I got no flashing curser. what do I need to check? this is a new calculator and I don't think that I did anything to it.

[@cynthiaspeed420]

help please, I am just trying to do the first exercise, graphing. When I go to Y1 and put in X and toggle over one space, and press graph the message I get is the "error:window range" . Is there a setting incorrect on my calculator? Thanks

[@isabelesparza4584]

I also have an error, trying to figure out what I am doing wrong

[@Dhrjzjannb123]

This is so helpful! Thank youuuu :)

[@hideyobaefromhydrobray]

Thanks! Algebra 1 is not going the best for me, I needed this

[@judahrue6793]

THANK YOU. I've been looking everywhere because I didn't know how to turn my T key into an X. apparently I wasn't in function mode.

[@KermMartian]

Glad to have helped! That'll do it.

[@stanlyzhang9980]

For finding the intersections. Does it matter where you put the dot for first and second curve?

[@KermMartian]

No, the only thing that matters is guessing an intersection that's roughly correct.

[@xxxxxxuan]

Great! How do I find the max/min etc on the graph? When I go to true function and press enter, nothing happens

[@pranavthammana4091]

This is super informational, thanks.

[@marquesmq7]

I have been using TI-83 for tree years now and it's basically the same thing except the color display

[@kper8145]

Mariana Marquet that's what it is I believe the original 84 only added a few functions, and this hasn't changed much since then.

[@KermMartian]

"Tree" years? :P Yeah, the math features of the TI-83/TI-83+/TI-84+ series have changed very little over the past twenty years or so, mostly due to teacher feedback that there aren't very many extra features that would enhance the pedagogic value of the calculators.

[@ashe4702]

Thx. Im using a hand me down, and I dont know where my big sis kept the manual😅

[@franandwood14]

I keep getting “invalid dimensions” and I don’t know what I’m doing wrong

[@KermMartian]

Please watch the Troubleshooting part of the video (8:07).

[@weyderwarr]

Anyway to reduce padding around the graph? I feel like the big display and high res is not taken advantage of. I realize there needs to be room for coordinate labels etc, but, either way, it does bother me slightly.

[@KermMartian]

+LyyK Unfortunately, no, you can only graph within the 265x165-pixel area due to limitations from the TI-84 Plus C Silver Edition that were brought forward to the TI-84 Plus CE.

[@joycemurray4158]

I know this video has been out for a while, however I need to know how to clear my history on the graph.

[@KermMartian]

You can clear the graphed equations by going to [Y=] and hitting [CLEAR] on each line. You can clear the graphscreen itself with ClrDraw. Go to [GRAPH], then [2nd][PRGM] (the Draw menu) and select ClrDraw.

[@joycemurray4158]

Thank you, I have just started back to school ( at 59) our video helped me understand the basics.

[@KermMartian]

Good for you! I'm glad to have helped.

[@rinnace]

i learned how to use desmos in online school last year, but now i need to know how to use a physical one. i'm so confused.

[@Geopipe]

Good luck! Hopefully the videos and/or the book help.

[@AndrewGulickTrueVitalityPlus]

OK, the flashing curser finally showed up after I entered the graph for Y2 = X Squared +3X+1 and hit graph to place the parabola into the graph. I got all three flashing cursers now. Not sure what the deal was with just the sloped line.

[@KermMartian]

Weird; glad you got it figured out.

[@catmallon1145]

KermMartian: Like your video. Maybe you can help me troubleshoot my student's issue. When trying to type in y=4x^7+5x^4+2 to graph, everything is staying in the exponent mode after the 7, even after hitting the right arrow and retrying. We even cleared RAM. Thoughts? It's either the TI-84 CE or CE Plus.

[@KermMartian]

Hitting the right arrow after the 7 should indeed do the trick to exit the exponent entry mode - you'll see that the cursor changes from a small superscripted box to a larger box. If it still won't work, you could also try going to [MODE] and switching from MathPrint to Classic mode, which will allow you to enter the equation in a simpler form (no fancy exponents).

[@mickmoto17]

I'm a sophomore in Algebra 2 and Chemistry and I want a calculator I can use all the way to college. What would be a better option, the TI 84 plus CE or the Casio prizm?

[@mickmoto17]

Btw We use Casio prizms in the math department but TIs in the science department

[@manda7271]

may be a little late but the ti 84 plus ce

[@andoro_C]

is y calc possible

[@KermMartian]

Yes: you can either just swap X and Y in your equation, graph it, and interpret the dependent Y values as X values, or you could rearrange the equation from x=f(y) to y=g(x).

[@armando4elmundo]

Hey Christopher! Thanks for the TI 84 vids. Just getting to know my new 84 Plus CE. I want to do a problem in Pre-calc 12 where you graph the speed of sound which is 20 times (the square root of T, for temp in Celcius, + 273). I need to change Xmin to -285 and Ymax to 400, but I get an error message when attempting to change Xmin from -10 to -285. Can you help?

[@KermMartian]

+Armando Weiss Make sure you're using the negative symbol (the [( - )] key) and not the subtraction symbol (the [ - ] key). Check out Part 1 of this series if you need a refresher on things like that. :)

[@maribelescaros5803]

I know this is an old video but I really need help in fixing my calculator. I was trying to clear all lists in my calculator but now I am unable to graph anything. How do I fix it?

[@KermMartian]

Four years ago is hardly old! Go to [Y=], use the arrows to move the cursor to the top of the screen, and deselect Plot1, Plot2, and/or Plot3. See 8:10 in this video for more info.

[@jellybeans3888]

This video helped me with a lot of problems, except about a second after the graph has been drawn, I get a syntax error and it says check all arguments entered pls help :,(

[@KermMartian]

It sounds like you entered a second equation by accident. Choose 2:Goto when that comes up, and delete Y2's contents (or whichever equation it is).

[@jellybeans3888]

+KermMartian thanks

[@rishabhbhattarai6358]

when i press Y= it brings up this thing that says nMin=1 u( n ) = and some other stuff but it doesnt show the Y=

[@jackalninezeronine]

Awesome videos, man! Thank you for uploading.

[@maribelescaros5803]

Hi, it’s the same person as three days ago. I’m new to the calculator and keep on doing something wrong that ends up breaking it. My calculator isn’t letting me graph anything with a negative sign in the front of the equation. To clarify, it won’t let me graph y= -2x for example. How do I fix that?

[@KermMartian]

You need the negative sign (the [(-)] key), not the subtraction sign ( the [-] key).

[@daisyscovens9400]

I am currently viewing this tutorial and when I do the y=x and press graph I get an error not the graph with the blue line why is that?

[@daisyscovens9400]

[@shaanaem3434]

When I hit the graph button an ERROR: INVALID DIMENSION keeps showing up with a bunch of grey writing at the bottom so can I get it to graph?

+Shaanae M Take a look at the last part of the video, where it explains how to handle the INVALID DIMENSION error.

[@hermegonzalez1335]

How do I make multiple graphs everyone I try and make a second one it says "only one function and up to three plots will graph. Press graph, and then it only graphs one instead of both

I just need to know how to go to the initial page , I'm on archives and Idk how to go back without deleting the things I've written on the archives

[@KermMartian]

If you mean that you're in the [2nd][+] (Memory) menu, you can just press [CLEAR] or [2nd][MODE] (Quit) to return to the homescreen.

[@nsalerno88]

I have this calculator now too and every single time I try to graph more than one function it says " Transformation graphing- Only one function and up to three plots will graph. Press graph" and then I press graph and it only graphs the first function...

[@nsalerno88]

+Nick Salerno I figured it out

[@iCarlee708]

How did you fix it?

[@nsalerno88]

+Carlee Koldyke click apps and at the bottom it says transfrm, click that and it should ask if u want to quit transformation graphing, quit it and bam you are good

[@iCarlee708]

+Nick Salerno Thank you! 😊

[@jasomeli]

Any idea of how I change and use less than equal to, greater than equal to? On the 84 plus ce? I want to use these symbols when graphing but I am unable to find these symbols. I moved left from the y= button and cycle thru the signs but they never pop up. Any suggestions??

[@KermMartian]

Apologies for the slow response. You'll need to install Inequality Graphing (Inequalz) from TI in order to get those symbols in the Y= menu. If you have it in the App menu, run it to enable it; otherwise, you'll need to download it from education.ti.com .

[@EvoZimsHQ]

Is it possible for the calculator to tell me what the period, asymptote, phase shift, etc. is from a graph?

[@KermMartian]

+EvoZims Yes, but not completely automatically. For example, to compute the period, you need to use the [2nd][TRACE] (Calc) -> Zero tool to find the x-coordinate of two x-intercepts, then subtract one from the other. For the amplitude (is that what you meant by asymptote?) you can use the Calc -> max tool.

[@EvoZimsHQ]

+KermMartian thanks; amplitude is what I meant!

[@locke3862]

how would I graph an equation such as x=(y^2-8y-84)/20 on this calculator?

[@t2lacademy614]

Hi! I think you would have to change it to isolate the y on one side, and then graph.

[@user-yr3uj6go8i]

My calculator doesn't graph anything... Edit: Nevermind, just fixed it a few minutes later just by clearing RAM.

[@KermMartian]

Glad you were able to fix it!

[@daphnestephens2431]

I have the ti-84 plus and I'm trying to graph an exponential graph. Every time I put in the exponential equation and graph it, it shows a linear graph. How do I fix this?

[@KermMartian]

What is the equation you're trying to graph?

[@daphnestephens2431]

The equation is P(t)= 18,000× 0.988^x

[@KermMartian]

Surely you mean P(x)? As written, P(t) is a constant, which would explain the straight line you're seeing. If you're in rectangular mode, try entering that equation as Y1=18000*0.988^X.

[@daphnestephens2431]

Sorry for the confusion, that's what I meant. I tried typing in that equation to graph it, it ended up being a straight line instead of a curve. I'm pretty sure some setting is messed up, but I'm not sure which one it is.

[@KermMartian]

Are you definitely in Rectangular mode if you check [MODE] (or in Y=, is the first line Y1=)? What is your Window (in the [WINDOW] key)? Note of course that that line is going to appear very close to linear, since it's close to c*1^x but isn't. I recommend you adjust the window to something that will have wide X bounds but narrow Y bounds to accentuate the curvature.

[@TheZod00]

Why does the calculator say invalid dimension whenever I try to graph something. Even when I tried to graph just x it said that.

[@KermMartian]

You have a Stats Plot enabled. If you watch through to the end of this video (or read the book), it explains how to fix that.

[@u2s5thmember]

I enjoyed your video. Thank you for uploading. Do you know if there is a way to graph X=2y-y^2 for example (really anything as a function of y)? Thanks again!

[@KermMartian]

Unfortunately, there's no built-in way to do that, although TI provides an App that has that functionality.

[@Umbravenator216]

when i entered the x^2+3x+1 and hit graph it only graphed the y=x line. how do i get it to graph both lines?

[@KermMartian]

+David Radtke Make sure the that equals sign (=) next to the graph is white on a black background, which means enabled. If it's not, move the cursor to it, and press [ENTER]. It will change from black-on-white to white-on-black. You can also disable graphed functions the same way.

[@Umbravenator216]

+KermMartian okay i made sure both y1 and y2 were enabled and now when i press the graph button it says in a pop up window in the header of the window "transformation graphing" and in the body of the pop up window "only one function and up to three plots will graph. Press GRAPH."

[@KermMartian]

+David Radtke Aha, you enabled the Transformation Graphing app. When you're in the Y= menu, move the cursor to "QUIT-APP" and hit [ENTER].

[@Umbravenator216]

+KermMartian nevermind i figured it out :)

[@pixidst2011]

when I try to graph it goes to error screen. says check values in window??? what do I do?

[@KermMartian]

It may sound obvious, but press [WINDOW] and make sure that the values there make sense.

Does anyone have have any idea how to enter domain and range restrictions on graphs?

[@KermMartian]

Apologies for the slow response. You can control the domain: on OS 5.3 and later, you can explicitly set the domain minimum and maximum; before OS 5.3, you can do this via something like: Y1=f(X)/(X>=domain_min and X= and "and" can be found in [2nd][MATH].

[@riccardob6921]

HOW CAN I PUT X=3 (for example)?

[@KermMartian]

If you're just trying to set a variable, use the store ([STO>]) key in the lower-left of the keypad. For example, [3][STO>][XT0n] will produce 3->X, which will store 3 to X. If you're trying to compute the value of a function at a point, though, you'll want to do something like Y1(3).

[@riccardob6921]

KermMartian My intention is to see the graph of the function x =3. However, when i try to write the function i can only see y1 = etc.

[@KermMartian]

Press the [ZOOM] button, and choose ZStandard. If after you do that you still get an error like ERR:DIM, or ERR:UNDEFINED when you press [GRAPH], then review the troubleshooting part at the end of the video (starting around 8:00) where I talk about turning the Stats Plots off.

Does it come with a warranty?

[@KermMartian]

If you mean the calculators, they do come with a warranty. Why?

[@user-rc9jf8ng2k]

No, actually I was wondering if the manual/book comes with a warranty in case I accidentally put it in the washing machine or set it on fire leaving it on the stove or something; because I wouldn't want to pay twice. I want to have the manual for a quick reference from time to time, but I don't want to have to constantly replace it (out of my own pocket) when accidents happen.

[@KermMartian]

Haha, I'm glad you found what you were looking for. For future reference, the authoritative source of information is TI's own website: see "Support" in the "Specifications" tab: education.ti.com/84ce

+KermMartian that worked thank you so much

[@ElementGuns12]

how do you clear a graph?

[@KermMartian]

ClrDraw (from the [2nd][PRGM] (Draw) menu) will clear any annotations on the graph but leave the graphed functions there. If you also want to get rid of the functions, go to [Y=] and hit [CLEAR] on each line that has a function defined.

[@alanguerrero3903]

When i put x it wouldn't graph

[@ruthieer4015]

The same thing happened to me

[@kimberlywhatevervids3106]

You guys may be using the wrong X. Don't use the green (alpha) or blue (2nd) variables. When in the y=, you'll be using the button that says "X,T,0n". Just press it once for the X to show up in your equation.

PRICE

[@KermMartian]

PRICE OF WHAT? :) The book is about $17 - $25 depending on where you get it ( www.amazon.com/dp/1617293156 ), and the calculators generally run around $100-$120.

Hiw do I get decimals on my table

[@KermMartian]

Do you mean the the graphed function table, from [2nd][GRAPH]? If the function has a decimal domain or range, it will show them. If you want to adjust the spacing of the X values in the table, go to TblSet ([2nd][WINDOW]) and change deltaTbl (the little triangle followed by Tbl) to a different number.

Put the play back speed to 0.75x

[@KermMartian]

You can always rewind, or just read the relevant chapter in the book. ;)

I'm sure you can find weirder videos than math education videos.

So I was given 2 points wich I know how to graph and I graphed them but I need to find the coordinate that is 2/5 of the line how do I do that?

[@andriaxu4496]

Whenever I try to graph something (y=x for example), it says "Error: Invalid Dimension" ... any tips?

[@KermMartian]

The answer is near the end of this very video, around 8 minutes in.

[@andriaxu4496]

@@KermMartian Ohh I'm sorry; Thank you so much!

[@biq]

Help me please!! My graph is totally white for some reason, I can see graphs (color lines) but can't see the axes...

[@KermMartian]

Just go to Format (2nd, Zoom) and select AxesOn.

[@britts125]

Not sure why this isn't working but by simply putting x in for Y1 and clicking graph, I get the graph screen but it's blank and no line is there help?

[@KermMartian]

Brittany Peters check the Window settings - the graph and/or the axes might be off screen. if in doubt, go to Zoom and choose Zoom Standard. you can also turn the axes on and off in Format (2nd, Zoom).

[@britts125]

KermMartian okay thank you, that worked. The x min/max & the y min/max were so small that the graph wasn't showing up, but it works now. Thanks again also for the informative video 👍🏾

[@KermMartian]

Happy to help! I'm glad you were able to get it working.

[@angellacruzz]

when i hit graph it tells me error:invalid dimension:( how do i fix this

[@natalieschoenn]

I had this problem too! Just deselect "Plot 1" at the top so non of the plots are selected :) Hope I could help!
