TI-89 How to Solve Equations

[ZekeDaG33k]

but how would you solve a four step equation? or atleast a three step?

[wheely132]

@ZekeDaG33k can they do 4 and 3 step equations?

[444zane3]

this calc is pro!

[ZrxV1]

haha, you're one of the few ppl i actually thank on youtube..... I've been trying to figure out how to solve equations on the ti89, but I never knew u had to put the comma and variable at the end... thank you

[iven101101]

thank you for ur sharing, i learn a lot from ur video... thousand thank you

[rodrix50]

Is there a way to get step by step equation s solution wtihout putting a program?

[5N3RF]

@rodrix50 somebody need a calculator to do homework eh?

[rodrix50]

@5N3RF haha kind of...

[5N3RF]

@rodrix50 Only reason to buy a 150 dollar calc...or if it had fellatio capabilities.

[rodrix50]

@5N3RF actually i didnt buy it , my brother gave it to me .. lol

[eliassami5]

WOW...ive been trying to figure out how to use the solve function on my 89 for ever..never thought of putting a comma and then the variable lol. Thank you for that.

[AlucardZero]

I got the answer faster in my head for this easy equation >_> -2.5 But for harder problems this thing would be so awesome.

[KSAzone]

OMG If I know About it in high school, I'd like to buy it

It solves every thing !!! ^_^

[DragonsKing91]

@KSAzone u can only use this cal in some class, like physics and calculus (some profs dont even let u use it in calculus 1 mabye 2 or 3 and DQ). So i dont think ur teacher in high school would let u use this. lol

[babou1234567890]

@DragonsKing91 I used it in Pre Cal. I had nothing less than 95/100.

And everybody would think that I'm Genius :)

[mauricioreloaded]

thank you very much !  so easy :)

[arenics]

HP 50g do it more clear and has more flexbilty.

[navyhermano]

how do we run the programs on the ti 89 because i had the ti 84 and it was much simple just press enter in the program but on this one i don't even know how to find it in the calculator. great video

[robymoma]

I believe you press the "2nd" button and then press the minus sign... but i'm not really sure if that's what your'e looking for

[navyhermano]

nice work

how do you convert decimals to

fractions

[robymoma]

Simple. "Highlight" the answer that you want to convert to fraction and click the green button with a diamond in it and then press enter. :)

[MrShootinputin]

Thank you so much man. 5 stars.

[hooooopty]

Thanks homie!

[axelasdf]

It is TI-89 (tee-eye-eighty-nine), not T1-89 (tee-one-eighty-nine)

[Yu2Kal]

lol yea i laughed when he said tee one

[enter19]

by the way thank you i didnt know that

[vdub350]

@enter19 The "solve()" function is so much more powerful. You can do a lot with this calculator.

[enter19]

what else can you do, like more complex? thank you

[enter19]

are you colombian?

[akwlb2]

cool thx i didn't knew you could do that with the calculator

[Shamobii]

Thank you, short, to the point, clear, great!
