Sinx cosx formula

sin(x - y) = sin(x)cos(y) - cos(x)sin(y). Or more generally,. sin(x ą y) = sin(x)cos(y) ą are the reduction formulas (identities) for sine and cosine. They are valid for both degree and radian measure.

= (Rcosα)sinx + (Rsinα)cosx. The coefficients of sinx and of cosx must be equal so. Rcosα = 1. Rsinα = 1. Squaring and adding, we get. R2cos2α +R2sin2α = 2 so R2(cos2α +sin2α) = 2. R = √2.
