Lol forgot to add the equation... Could anyone tell me how to prove this/which is the right way to begin or anyway sort of system that you have to get the proof generally? Sin^2x+3cos^2x=2+cos2x

Many different ways for this now you may want to start with a 2 side length equilateral triangle and square of sides length 1 divided both by 2. And know your common angle table. The rest I don't see why you would ask this as they are always different unless a semicircle divided by two and you are told what to use
