Step by Step Calculus on the TI 89 and Voyage 200

See how to solve Calculus problems step by step. I.e. Step by Step Derivatives, Step by Step Integrals, Step by Step Differential Equations.

Just enter the function and see the details of how the final answer is derived. Really amazing.

Hey bro I have this calculator but when in normal function mode there is no graph lines... It is really annoying any help?

[kramed8]

Sorry, not sure about that.

@regaz93 check the zoom, make it zoom out

The thing with the ti-89 is that you don't get "pretty print" until you're done with the problem and it goes into the history stack (think about it). The whole time you're entering a large, complex equation into the command line, all you get is that tedious, one line format. With an HP50g in RPN mode, you get pretty print as soon as you start entering your problem. You can also input your problem in way fewer keystrokes with the HP. Something to think about.

Pretty print? It's CAS that makes modern calculator different. I have no idea why highschools use TI-84s and not TI-89s. Students need to see calculus rules applied. Calculus gives you the answer but you have to prove the answer. Why is this the answer? Application of the chain rule for example.

Is it just me, or are even the top-notch calculators overpriced and underpowered?

Really we should have way better calcs at this point. I have a TI- 94, a Voyage 200,and my little Casio fx-115ES. The Casio is way Overpowered if you look at what it can do for a $18.00 machine VS. the $140 or $170. you pay for the other two. I want a HP 50g, but still if I could dedicate my HP 4355 pocket PC to just calculations, it would toast them all.

which is better? voyage 200 or hp50g?

@rbdgirl12 haha so true

It certainly is a lot more feature packed than my old ti-83. That said, these problems should be second nature to anyone studying mathematics at the university level anyway and once you graduate you'll probably never touch a calculator again. Everything is done on PCs.

I JUST LEARNED HOW TO GRAPH IMPLICIT EQUATIONS!!!! without solving for y.

[boardrfolif3]

the best feature of the 89 is the "pretty print" refer to ti-89 wiki. If you don't need that I've found my 83+ sufficient, programs on the internet vastly expand the calculators use.

I found a ti-89 on craigslist for 40$ and couldn't pass it up.

The voyage 200 can do all that and cost 180-200 depend on where you buy it from.

and it's pretty awesome if you ask me .
