I have a new HP 50g, and am working on a small program that displays a definite integral on the screen. The one I am working on now is the definite integral for the area of a circle. With the push of a button, I'd like the program to display the unsimplified definite integral, followed by the simplified version (pi*r^2). Problem is, if I enter the equation in memory, it only displays the simplified version. I need some help on how to write a small program to do this for me. Thanks!
