i have been messing around with this problem for 3 hours, and havent been able to figure it out. its trig identities.

cos A / secA + sin A / csc A = sec^2 A - tan^2 A

the first half is two fractions. we can only mess with the first half and i cant get it to look like the second half for the life of me.
