Which graphing calculator is Better TI or Casio Also which model best for college math?

Texas Instruments graphing calculators are really easy to use and there are a lot of applications and programs available for the TI graphing calculator platforms (TI-83+ family, TI-84+, TI-Nspire, and TI-89 family). Thus, you will be able to easily find a program for your specific class (Calculus, physics, chemistry, etc.) at Texas Instruments app store and also open source program repositories like ticalc.org.

The TI calculators also are the most commonly used in the more advanced mathematics courses, including Calculus I,II,III, differential equations, etc. because they have all of the features and functions one would need in a easy to use, user-friendly interface.
