Trig Proof Issue..
I am currently smashing my face into my desk from frustration of this trig proof. People have told me it's easy, but for whatever reason, I can not for the life of me figure out how to do it. The problem is:
(sin³x + cos³x) / (sinx + cosx) = (1 - sinx cosx)
Any help with this would be greatly apperciated..
Thanks in advance! (Cool)
Do you remember the formula for factoring the sum of cubes.
