I got Maple 17 a few weeks ago and it has been helpful in my learning of calculus, but not as much as I had hoped.

I also bought the Calculus study guide which is a big disappointment. For example, I tried using the integration methods tutor for the integral  cos(5x).

The correct answer is  1/5 sin(5x) + C and is found with U-substitution. 

With the tutor, I entered cos5x into the function box.  cos(5x) does not work....
