Trig problem!!!How do you do cos(3x)=4cos^3(X)3cos(X)? I mean, I got to somehow transform the left side of the = sign so it looks exactly like the right side. Kind of like a proof. I think I need some of the trig formulas for this but I can't really get it... Thanks for any help! #2 20060107 11:52:53
