My code shouldn't have anything other than function calls in the main, I'm having trouble on how I can do this?

To give you an idea (one out of numerous ways to do it). I commented out for illustration. However, I did not verify the actual calculations.

Surely this code has appeared before?
@cash, your determination of smallx and smally in your lines 32 to 36 really isn't going to work. Update them separately.
