I’m migrating from a Casio and need to make progress. Thanks for providing these videos.

Thank you for your time and help. =)

@detheroc you will use e^ a lot more often, that's the reason. And it's simple to get an e, just press e^ and then erase the ^.

[@theodoresweger4948]

Very good thanks

[@DiskoSpider]

[@jaarmen11]

I am considering getting one of these. Did it come with the clock feature already installed or did you have to download that app?

[@watwab1]

thanks you for your help sir

I am thinking about purchasing the TI-89. I have one question is there any way that this calculator can be setup to do iterative calculations for a Bode plot of an amplifer output for Gain vs Frequency. I can do it one calculation at a time but it would take to long for a large Frequency range. I enjoy your videos. Thanks.

Can you tell us how to solve a system of polar equations?

[@jolemak]

Very good videos. I have difficulties solving polynomial function y= x^2-9/x^2+9 its keep teling me syntax error. What should I do? help

[@mebanuelos]

[@eurofilmkid]

this is NOT the ti89.. This is the TI 89 platinum. I just purchased a TI89 and the home screen is not the same...

[@jfresh2054]

doesn't matter if it's a platinum or titanium, it's still a damn ti 89

[@eurofilmkid]

[@jfresh2054]

[@dannywest749]

Go 0.5 the price...hehe

[@45sixtytwo7]

how do you implicitly differentiate on a ti 89

[@artilleryisbetter]

why won't it calculate (15)(sin300))?

[@fromixx]

or press 2nd->pi...

[@mattfuller2864]
