TI-89 Calculator - 01 - Overview Of The TI-89 Calculator

[@gavout1511]

SAT is today, and I need all the help I can get. Thanks for the video!

[@MaryDeanDotCom]

I love, love, LOVE this video. I had to buy two of these expensive calculators when my kids were in high school, and they have been sitting around for years. I TRIED to use them, but I couldn't even figure out how to compute 2+2. Now I can store variables and make graphs. I can't wait to learn Tables. Thanks!

When I was in high school , I had the TI-85 which was the best calculator available. A few years later, in college a guy in my calculus class showed me his cool new TI-89 (non-titanium) that could solve integrals. I think I ran out and bought one the same day!

[@Kaktussssssssss]

@Jason Jackson any chances you know whats the highest rank/dimension of matrix you could write in? Did it work with at least 6×6 matrix?

[@estherhaynie5458]

Thank you SO much for these simple instructions! I downloaded the pdf manual and couldn’t make any sense out of it. Love the step by step process as well as on your other videos♥️

[@Soodall]

I love U. Sooo Frustrated before watching this bc I’ve just started studying SAT2 math by myself but there was no way that I can learn to use ti89. U saved me XD

[@66hats]

The most powerful calculator ever, got me out of a few jams over the years

[@AC-iw8wu]

Absolutely. Have been using it since the first HW1 version, it beats the fancy nspire with its overkill document philosophy and silly key layout any day.

[@Smmmile]

I have this calculator and I really adore it. Recently though I have seen the benefit of having RPN (Reverse Polish Notation) on the HP range of Calculators. It would be nice if this calculator had that built in too.

[@Jun_DaWondaBoi]

helpful. btw I just finished the first video, and still have more than 50 videos left. Easy to buy, hard to learn xD

[@balazsjanovszki6672]

For 200$ idk if its easy to buy😂

[@nolanzeng8241]

@@balazsjanovszki6672 I bought it for $40 from some college student on Craiglist and I'm only watching this because I have SAT practice this week but I don't have a yellow school calculator with me at home.

[@CristobalRuiz]

I have had this calculator since 2003 and I still rock it!

[@Kaktussssssssss]

@Cristobal Ruiz does this calculator work with 6×6 matrix (or any chances even higher rank/dimension)?

[@theodoresweger4948]

Very well done, thanks just required a new TI89 and this helps a great deal...

[@theartst7992]

I remember I got this calculator sophmore year and used it up until college. I forgot about it and recently found it. Now im trying to relearn all its functions 😁😫

[@theartst7992]

@@pong7592 thats strange it should be -10.

[@somber_soul]

@@pong7592 use the negative button to the left of enter, not the minus sign.

[@JosePerez-ej1xe]

Great video! Good Work! It helped out a lot, thank you.

[@renewd]

Thank you for your helpful and clear presentation. I look forward to firther learning.

[@star7226]

Thanks!

[@MathAndScience]

Wow thank you!

[@TELong1603]

Does this calculator come with a good user's manual that takes you through the its use? Thomas Long

[@IExSet]

Alone with HP 50g it was last calculator ever created, top of graphing calculator evolution, next models are just handheld computers like smartphones with terrible usability. TI 89 Titanium (as well as HP 50g) is ultimate machine for learning math. They never create something better :-( P.S. Look at TI 200 Voyage it has almost identical OS, but full QWERTY keyboard and larger screen. Something like "desktop" calculator for serious courses :-)

[@lucasromeo3925]

Jason, do you have a link to a KZbin video explaining how to determine the equation of a quadratic, given a set of points in a table?

[@Abd.elmoumenMokhtari]

This video helped me alote thank you

[@avacyn2000]

Can it be used for Binomial approximations?

[@jasonzacharias2150]

Thank you Jason... Godspeed 🙏

[@SanthoshThanikachalam]

Its so sad that this calculator is not allowed on the ACT, which is strange considering it is allowed on the SAT and most state examinations.

[@hamzah4792]

thanks a lot dude that was useful

[@Smmmile]

Which is better, this or the HP50G or HP Prime? For a Career in Electronics/Engineering/Physics.

[@h.m.5724]

Definitely hp prime

[@Smmmile]

@@h.m.5724 It's a nice calculator. What would be your reasons?

[@star7226]

It is not only praising him try to donate a little bit ,so that we will make him a millionaire.He deserve it

[@MathAndScience]

Thank you so much!

[@naderhumood]

Thank you v much....Great job .one big problem, it doesn't have backlight.

[@palletpatrol3009]

I found one of these at the local thrift shop today for $5 😃

[@alyabayani871]

i want to know about modular arithmetic in mode key can you explain

[@dalobucaram7078]

Got mine in 2001 and still use it today. I also have it as an adroid app.

[@richardkmcmurtry]

where can I find how to multiply by -1 on the ti -89. I keep getting a syntax error. with 5 x (-1) Richad

[@abby83]

Richard McMurtry try using the negative sign (to the left of enter) instead of the minus sign

[@rayonchan824]

Very help thank you very much

[@mediaphile]

I never thought about how you can change ans(1) to be any other value up to 30 to recall a previous answer in the stack.

[@Thomas..Anderson]

Which emulator is this?

[@DoggyPilot]

Seems to be top secret…so this ass hole that narrates the video won’t tell anybody…

[@johnhenline5942]

Hope this works on the non titanium

[@user-su5sq5ib3i]

Can someone tell me withe the XTTheta button is on the ti 89? Thanks!!!!!

very nice

[@ajdelarojo9620]

How do I change it to scientific?

[@ingediana]

The menu is pretty ugly; our 87's casio fin calc had way better display. Should they'd at least doubled the res. (to cga320x200), I bet they could've doubled the sales even if they'd doubled the price.

[@tejpanchal3168]

Me after getting this : i m sintist ( i know scientist spelling, its for joke )

[@maxparsell7340]

I love you

[@gwenjapam3660]

I had a TI 36X pro....now I have this and I feel like I am cheating on my other calculator...

[@floridian2023]

W.O.W.

[@AnthemDrums]

I cannot beleive that you didn't simply show how to get the answer for division problems in decimal point....im not a math wiz. IU just trying to provide my 6th grade son a calculator to use in class, and we cannot get my old school calculator to solve division problems properly. I know 789/5.4. = 789/5.4. I need the actual answer....terrible video. You could have spent 5 seconds explaining how to use the basic functions, but you love multiplication and hate division apparently.....

[@mediaphile]

Hit the green diamond button, the one right under the blue 2ND button, and then Enter. It's labeled right on the Enter button as "≈" because it is often only giving an estimation as a decimal. Even if you forget, and it spits out another fraction, you can just press the green diamond button and Enter and it will run the same equation again and render it as a decimal. Preserving fractions is one of the strengths of this calculator, but it does mean you need an extra button press for decimals whenever you're working with fractions.

[@AnthemDrums]

@@mediaphile Thankyou. My son and I finally figured it out. It's frustrating trying to get a "super-calc" to do basic math, when it's been almost 32 years since I used the damn thing....However, it is a testament to the calcs quality that it still works perfectly!
