Hi,
I need to proof the following equation is true, e.g. that the left hand side is equal to the right hand side.
(sin2(360 - x) + cos(90 + 2x) + cos2(180 - x)) / (sin(90 - 2x)) = (cosx -sinx) / (cosx + sinx)
I only got this and can't go further:
(-sin2x-1) / (1 - sin2x)
Any help please.
ps. sorry for messy typing, dunno how to type fractions on this forum..
