What is the difference between the Texas instrument calculators TI-83 and TI-89?
There are quite a few differences. Well, I shouldn’t say a few. I should say a lot of differences. The main difference you need to know between the two is the type of things each can calculate. The TI-89 has a Computer Algebra System (CAS), which means it can solve algebraic equations, polynomial expressions, and perform symbolic manipulation. The TI-83 (Plus), however, cannot do those things because it does not have a CAS. Then there are other small things that may or may not be pertinent to you. Things such as listed here: http://en.wikipedia.org/wiki/Comparison_… Basically, if you’re going to major in mathematics or engineering, then the TI-89 would be more useful in the long run. However, if you just need a graphing calculator for a math class, then the TI-83/84/Plus/SE calculators will often be adequate. It depends on the course though, so you should check with the teache
