±[f(O) + f(±) + f(~) + f(%)]. = !(1 + ~ + l  We can write the expression sin(x+y) in terms of sinx, cosx, siny and cosy if we use the addition formula for sine,. sin(x+y)=sinx cosy+cosx siny.

For math, science, nutrition, history sin(nx) = 2 · cos x · sin((n − 1)x) − sin((n − 2)x). This can be proved by adding formulae for sin(( n − 1) x + x ) and sin(( n − 1) x − x ) . Serving a purpose similar to that of the Chebyshev method, for the tangent we can write: For sin (x – y), we have – sign on right right. For cos, it becomes opposite. For cos (x + y), we have – sign on right.. For cos (x – y), we have + sign on right right.
