Addition theorems for multiples of the argument value

sin(2x)=2sin(x)cos(x)

sin(3x)=3sin(x)-4sin3(x)

cos(2x)=cos2(x)-sin2(x)

cos(3x)=4cos3(x)-3cos(x)

Potencies of trigonometric functions

sin2(x)=12(1-cos(2x))

sin3(x)=14(3sin(x)-sin(3x))

sinn(x)=12n k = 0 n ( n k ) cos((n-2k)(x-π2))

cos2(x)=12(1+cos(2x))

cos3(x)=14(3cos(x)+cos(3x))

cosn(x)=12n k = 0 n ( n k ) cos((n-2k)x)
