Cos2X =(1-sin2 X ) -sin2 X (Since ,cos2X=(1-sin2 X ) cos2X=1-sin2 X -sin2 X. So. Cos2X=1-(sin2 X+sin2 X) Hence cos2x =1-2sin2 X. Cos2x =2COS2X-1. To derive this we need to start from the eariler derivation As we already know that. cos2X =Cos2X -sin2X. Cos2x=cos2X-(1-cos2X){Since sin2x=(1-cos2X)} Cos2x =cos2X-1 +cos2X.

sin4x = (1+V2)(sin2x + cos2x - 1). 2sin2xcos2x=(1+v2)(sin2x+cos2x-1) sin2x+cos2x=t. (sin2x+cos2x)^2=t^2 sin2x^2+2sin2xcos2x+cos2x^2=t^2. cos2x skulle jag hellre skriva som cos(2x), alltså Cosinus för dubbla vinkeln.
