How to use the SOLVER function on a TI-84

[@djuroradulovic1371]

This guys made tutorial in 2011, that is better than all tutorials today.

[@Art-iq3tf]

2021 and still relavent

[@R-Flowerish]

'cause he's awesome

[@benedictcumberbatch7229]

Why the hell aren't our teachers teaching us such things?

[@randomuser-vs3oe]

you dont learn that way.

[@Pintexx]

When you’re in high school taking classes before calculus you should get as good at algebra as possible so you breeze through harder classes in college. This silver can’t do everything remember

[@affapple3214]

Search Newtons Method, I think this is what this function does to find the zero

[@eclipse_pvp-gamez5428]

@@randomuser-vs3oe they teach us to use desmos.com but they don't teach us how to use the Ti-84 calculator for SATs and ACTs

[@jeremywilliams9288]

@@eclipse_pvp-gamez5428 I teach my students how to use it that way. I also teach my students how to find the answer on the table or graph. I am not sure about the SAT, but in the ACT you only have 1 min to answer each question and most students take too long to come up with the equation and take too long to type it in the calculator.

This video is old and cheesy...but I really love it LOL. Very helpful!

[@sharv33n]

You guys did great! Thanks for the help! Very entertaining and very lively. Keep up the great work :) It doesn't matter what type of TI you have, they all have the same basic layout. Just follow what they did and you'll figure it out. I used this tutorial to figure out how to do this on my TI-84.

[@DrAnjali_Sharma]

Needed this for tomorrow's chem test and this is the best explanation so far! Thank you!!

[@fratercontenduntocculta8161]

Thank you! I am getting ready to attend college for the first time, and math was always my least favorite subject. With a little help from my TI-83, (it has the solver too) I feel a bit better about going into college algebra!

[@snorky776]

Thank you guys so much!!! I was so frustrated reading the Manila for my ti 83 and was getting so frustrated!! You guys did an awesome job at relieving that stress! Thank you!

[@RustedLocket]

This is the TI 83. You have helped me almost as much as my Spanish teacher has helped me with quantum physics.

[@dyllans1225]

8 years and its still not too late to delete this.

[@sleepyguts128]

this vid was a life saver, straight to the point and insanely helpful

[@onety3578]

2024 and this is still the best video showing off this function

[@rebeccaburks6445]

Calc 1 exam had me shook, thanks for the help.

[@R-Flowerish]

If I had found this in 2011, I would probably say something like "This video is LEGEN... wait for it... ... .. DARY"

[@thebigboy284]

12 years later and this video is STILL helpful

[@Bob-ui2ct]

This helped me and I have a test tomorrow. Thanks guys

[@kittycatmeowface]

Wow, never thought a graphing calculator could do that...thanks, I always had trouble with those questions

[@dawnstiller]

It is a good idea to try a positive guess and a negative guess, but sometimes the equation will have two positive answers or two negative answers. If your calculator gives you "Err: iterations", it means that are no answers with the sign you've entered. Try a guess with the other sign to get your first answer. Then try another guess with that sign (either closer to zero or closer to (+/-) infinity) to get your second answer. For instance, if 1 was an answer, but there are no neg answers, the -1 will yield the iterations error. Then try .00001 (which is much closer to 0); if that still gives x=1, you have not yet found your second answer. In that case try 100000 (much closer to infinity), and you will get your 2nd answer. Using very large and very small 2nd guesses will eliminate too much guesswork.

[@JonBergmann1]

Great advice

[@collaide]

My calculator just says: 0=0 Bound= i can't write anything anywhere else except next to bound

[@sublimesense7761]

i know right. This $100 turd cant even do algebra

[@shejan0986]

What was your equation

[@THEREALTISH76]

Thank you, first video that was straight to the point. Very Helpful

[@HudsonDavenport-j7g]

You are inspirational.

[@JoseDiaz-er4ww]

Hahahahaha it's so funny to watch this kind of tutorials!!! I forgot how tu use this feature on my TI-83 +, and suddenly a problem appeared, I had to solve a 4th. grade polynomial equation!!! I could solve it finally (well the calculator did it). Thank you.

[@alexandracabbiebie3026]

Thank you so much :, ) HAHAHA. Maths test soon and I was angsting over this, unable to sleep. so yep, thanks! ^^^

[@Lyreoz]

Thank you, I wish they taught this in school, though this does give me a major advantage :)

[@VVerTTeXX]

bloody useless solver

[@braydencannon4011]

haa

[@Shyzah]

the solver on the casio fx 115es is the most amazing thing ever. A little slow, but gets the job done always.

[@lukejagg]

@@Shyzah so true! I always wished other calculators (like the TI84) had a solver like it

[@PCFirex]

That's cool! Thanks for the video! Very useful for my calculus class

[@LouisEmery]

Thanks. My kid didn't realize she had to press the green "solve" button. She thought the "Enter" button was enough. I don't blame her..

[@rpkgods]

god this would of been great to know this years ago... would of been so freaking helpful, but in college now, maybe it will still help, thank you for the video

[@alexosti3261]

You are my hero!!

[@8015908]

If only I'd knew of this sooner.

[@luiscarvo-mo7ok]

Oh, thank so much. You are the best guys!!!!

[@ExcelTutorials1]

You are such a homie. Thank you!!

[@irenneeettt111]

I am so confused, but what if I get an equation that I have no idea what to guess? Maybe 1 answer is around 5 and the other is around 300?

[@jesse578]

well its a guess, you can realistically put any number. I just tried putting -1239014524 where the answer was .5 and it got the right answer in about 1s. Guessing is to slightly speed up the calculation time by having it start guessing possible x values close to your guessed value and then expanding from that point. It's useful since the processor isn't that great so it wants all the help it can get to be as fast as possible.

[@joshman844]

You've made my life significantly better. Here try x+1=my life is better+1. Solve for x.

[@JonBergmann1]

Glad it helped

[@atlma2]

OMG thank you for the video. Explains so much.

[@JanetTheTech]

thanks guys, i needed a remender for that. awesome video

[@norxcontacts]

Thank you for the explanation, I could've sworn there was a better solver on the TI calcs.

[@do-m3126]

Love the energy this is amazing

[@leowiesauer6228]

You saved my ass😂😂, thanks i didn't know how to use it and that the 8 has to be on the other side

[@Unkown-Identity-h4u]

Thank you for the explanation: The solver is nsolve. That means, it usually stops at the first solution. To get another solution, you must get another range. The first guess was 1 and the solution was 0.721..., so the second guess I set to -1 and got -0.479. So the equation has 2 zero points. Another way is to graph the function to receive a hint for the solutions

[@buzzfeedright4154]

God bless you for the help.

[@hoangtran4736]

for some reason scientific calculators are almost always better than graphing calculators when it comes to solving problems. many even have built in quadratic and polynomial function solvers. the only reasonably fast way to solve a function on a graphing calculator is to graph it out and see where the lines intersect.

[@seinfan9]

is there any way to get this thing to find complex roots?

[@harry7164321]

Awesome! is there a way to do this showing irrational answers as radicals?

[@RATENIGHT]

OMG TY !!!!!

[@jeffreyzhang8839]

u guys need more views lmao thanks for the help!

[@superspinosaurus1]

Or you could make a program... Like this: PRGM: QDFRM Prompt A,B,C Disp (-B+√(B^2-4AC))/(2A),(-B-√(B^2-4AC))/(2A) And you'll both answers... (Note: This only works with Quadratic Formula)

[@forrestphillips6035]

Thanks so much. Does it matter what you input for your "guess" if you know there is only one answer to the formula you're using? I wanna use this to find answers quicker for complex problems, not just for quadratic equations.

[@emansaxon9447]

Unless it's like a cubic, quartic, or quintic

[@xoppa09]

nice video, wish i had found this earlier

[@terryma1215]

Are there any advantages doing this vs typing it into y= and get the zeroes?

[@andredesousa96]

Thanks!! Much appreciated!

[@sarthakagrawal1372]

thanks for the video..i was running pillar to post to learn solving equations on calculator

[@wiiu42]

Well, now I feel stupid. IT WAS RIGHT THERE!!!!!!!

[@cabbage-soup]

Hi! Do you know how to find multiple solutions?

[@264aub]

Thanks! Love the bow tie

[@MsnMarvin]

Thank you man. The TI is a bit weird for a beginner

[@kikimen1077]

How did he make up -2 and 5🤔

[@nickelodeontv2579]

this video is super helpful

[@Yanate1991]

Very good tutorial

[@zestokhazix]

you guys are legends

[@jamesz3361]

is there any way without guessing?

[@notsofi7282]

Is this a TV show?

[@carloscarruci8492]

How make It if i have more than 2 variables

[@johnchang1226]

mine is TI 84. when I press B:solve, I don't see the E1, E2 boxes, why?

[@alienponer4117]

this is specifically for the 84 series the process is different on the 89/92 series

[@JonBergmann1]

yes it is a bit different on the 89/92 series

[@korukuzey3248]

How can I store an answer from the solver?

[@JonBergmann1]

It is stored in the x value of your calculator automatically

[@sep_shrk]

Thanks , actually I don't have TI84 ( I've got Casio ) But I've got the IDEA and I could find it in my own , thank you guys !

[@skinnymon123]

is there a way to do this for imaginary roots as well

[@JonBergmann1]

I'm not sure how to do that -- sorry

[@christiansayers4951]

cheers lads, helped a lot

[@ikhlasabuthair3088]

My teacher probably doesn’t want me to know this THANKS

[@everglade7764]

Thanks!

[@worthplayingfor2197]

i cant tell if this is as significant as i think it is. i feel like this is huge and an amazing way to check equations but i could be wrong and maybe im missing something.

[@JonBergmann1]

You are right! Check away!

[@crh9801]

Thank you so much!

[@ginsengsniper1]

excellent vid, but you should change the tagline to Ti-83/Ti-83 Plus since that's what you're actually using.

[@Airguitarfooker]

You don't need to guess the answer that you think is closest, just write like a high number, maybe "80", and then solve, and then try "-80" a negative number.

[@stacilarey5320]

Thank you, thank you, thank you!!!!

[@vasquesvfcpt0161]

thank you guys

[@darpmosh6601]

Wait.......what if you want to store that x value

[@haggerd5007]

So that means a graphing calculator can solve any math problem? And can it be in any type of graphing calculator ? Plz reply

[@JonBergmann1]

Almost any: Those that are solvable... :)

[@sharkkick2894]

Thanks

[@JonBergmann1]

No problem

[@Sugarlegg]

I keep getting a syntax error...I'm using this to solve equilibrium expressions in AP Chem, and our teacher told us to figure out how to use this on our own, haha

[@AmandaSemiHealthNut]

THANK YOU THANK YOU THANK YOU!

[@willhanleyreed1990]

Wait. So you have to guess, and then it will give you an answer close to your guess? I thought equations usually only had one answer.

[@JonBergmann1]

Not all equations have one answer. For example: X^2 = 16 has two answers. x= 4 or x = -4

[@buenosdiasfederales8641]

you guys are fucking saints holy shit thank you

[@sourpatch4209]

Need this for my finals wish me luck🙏

[@JonBergmann1]

Have a great final

[@bewtnewt]

oh yea. we passing our exams with this one boys o7

[@juansinaaaaaaaaaaa5402]

can you turn the answer into a fraction?

[@legionmammal9785]

*Bold* words are 2ND _Italic_ words are ALPHA 1. *QUIT* 2. MODE 3. DOWN 10 times 4. RIGHT 2 times 6. ENTER 7. MATH 8. _B_ 9. UP 10. Enter in the equation 11. ENTER 12. Change bounds as necessary 13. _SOLVE_ 14. Take note of the number after "■X=" 15. *QUIT* 16. Rewrite that number 17. ENTER 18. Enjoy!

[@wtfisitpjur]

The bad thing for this is that some schools/classes/exams require the EXACT answer, so using the solver won't be needed; it has to be done all by hand.. Or by a real symbolic calculator.

[@Momokaka]

how can I calculate indices problems ？

[@JonBergmann1]

not sure. I imagine there is another video on that.

[@AlfaHanen1]

Thank guys, But it dosent work on my TI-84 Plus, to get the to answers. x1= I get but not X2=? Show us how to do on TI-84 Plus

[@kevinklose]

Thank you!!!

[@zamansmail]

Very useful

[@JonBergmann1]

Glad to hear that

[@htcjunkie16]

@guitarman1568 because it is not CAS.

[@626Link]

Wish I knew this in highschool Thanks

[@amrouf2748]

YES!! THANK YOU!!

[@silly_swimmer6613]

*me finding this video before my sat 🎉

[@erik0magic0]

nice video :)

[@justinfrix]

My output is wrong. It says the answer is x=0.587 for everything..

[@broccoli.invasion]

after filling in the formula push enter. then it says x=... and bound ... fill a number in at x and then push alpha-solve . then it calculates the answer

[@frederickdietz3148]

Can you tell us how to factor on a ti-85? Not solve, literally factor. Im lazy and don't want to do the steps.

[@Khono]

Thanks!!

[@eLemonnader]

Thank you guys so much! I like math now! lol
