Query: Excellent! A remarkable graphing calculator!

If you are pre-med student, you probably need a more basic calculator than this. However, if you are in engineering or calculus, this is a must for you! I utilized the T-89 for a calculus class and it improved my marks significantly! The instruction manual is superb, it whisks you through the many functuons of this calculator. Don't program the Serpinski triangle command lines they furnish in the manual, due to the fact it will devour your batteries!
