alternate solution multiply them with something that will make a common denominator we wanted to have a common denominator of sin x cos x therefore cos x cos x sin x sin x (cos x )^2 + (sin x)^2 1  .  +  . =  =  sin x cos x cos x sin x sin x cos x sin x cos x whats 1/sin x =? also 1/cos x ?

Although i don't see how you get COS(X)^2 + SIN(X)^2 1  =  SIN(X) COS(X) SIN(X) COS(X)
