# Calculators Reccomend a good Graphing Calculator

1. Jul 19, 2009

Well, i felt ambitious and signed up for Honors Precalculus. I think i will be fine considering i love math and physics, but i need a good graphing calculator. Around $100-150 if possible. And it would be nice if it had normal physics and math constants in it (since i am also taking physics next year). Thanks in advance. 2.

That is mainly what I use my graphing Calculator for). Physics contents? You mean like scientific constants? Most scientific/graphing calculators have them. If you mean programs, you need computer software(MATLAB, Mathematica,etc.) but they are much more expensive than what you could afford. 3. Jul 19, 2009 ### um0123 I wont? It seems like everyone in my school at the precalculus level has one... Can you still reccomend some? I want to be prepared and im sure it would be good to have in my senior year. I dont mean programs, because i would need to take this to school. Plus we have a lot of those programs on my school computers. 4.

At that point needing to know how to graph e-t*sin3t by hand isn't that vital....knowing what to do with the function's graph is. If you really are looking for a comprehensive calculator try the TI-89 (Titanium) or HP 50G. I have the TI, and I can vouch for it from personal experience, but I'm sure the HP is fine as well. 5.

TI Nspire, TI-84+(it's a bit cheaper), HP 50g, Voyage 200( which is like$200, but the best one on the list).

Also if you are REALLY interested in math/physics, then you could get Mathematica (It's like \$300. But It's fun to play with.)

I was just using it as an example. You can pick another function that is more difficult, ti doesn't really matter. That one came to mind from a Differential Equations test that I took recently.

TI-83+ or TI-84. Good deals always are offered during "Going Back To School" time.

You don't really need graphing calculators in Pre-Calculus or College Algebra, but they can be very nice for checking some of your work.

I forgot, the Casio ClassPad 300, is probably the coolest graphing calculator! It uses a touchscreen!

Edit: If you get it, make sure you get the "plus" version.
