TESTIMONIALS:
1) "Calculus Made Easy is a must have program! It shows step by step solutions to integration and derivative problems! I studied for the 2nd exam using Calculus Made Easy and I received a 93 on my exam!"
2) "I bought your TI-89 calc program, and I like it a lot. Well, that is an understatement, it is quite possible one of the greatest things I have ever had. It has allowed me to check every problem I have had in my college
class, and because of that I am at the top of my class."
