Hi.(adsbygoogle = window.adsbygoogle || []).push({});

So, for the first time my younger sibling will need a graphing calculator for their classes so I'm giving them my TI-84 Plus and getting myself a new, better one. Right now I'm a Junior in high school taking ap-chemistry, ap-physics and ap-calculus AB. Next year I'll be taking calc BC (my school has AB as a prerequisite to BC).

I'm looking for a calculator that will last me through high school and college, maybe longer. So far that turns out to be the ti-89T and the ti-nspire cx cas. I read on the HP 50G but I wont feel comfortable trying to use it's RPN input method when I'm the only one in my classes (and school) using it.

When in college I plan on taking the highest level math courses available (I love math, lol) and majoring in engineering (probably computer engineering and electrical). So, which calculator should I get?

I understand that some people will say that these calculators are bad because I will rely on them to do the work for me rather than understanding the concept myself, but I will not be using them for this purpose. I will be using them to mainly check if my work is correct or not after I have finished it, and stuff like that.

So, which one and why?

Thanks!

EDIT:

I've read several forums on this same topic but none of them have actually told me why I should choose one over the other. They all have mixed feelings, so I don't know which to choose. What are the pros and cons of both?
