Help With Solving Trigonometric equations (sin x)^2−5sin x cos x=0 What would be the first atep to solve this. I normally get the equation into a quadratic one but I cannot seem to spot the first step here. What I mean by (sin x)^2 incase there will be confusion is "Sin squared x" Appreciate any help.
