Because it's -sin to begin with. I knew I was making it too hard. Thanks.

When I plugged those in then I get cosx[SIZE="1"]2 - sinx[SIZE="1"]2 = 1 and then I get completely lost.

cosxcos(-x) - sinxsin(-x) = 1 I know I'm making it harder than it is, but I can't seem to figure it out. Any help would be appreciated. [FONT="Comic Sans MS"][SIZE="3"]RaveN
