Simplifying sin and cos
WebbThis means A = 3, and B = -1. Let's start by equating our original expression with the target expression: 3cos(x) - sin(x) = Csin(x+e) The first trick is to expand the right hand side using the general rule sin(a+b) = sin(a)cos(b) + cos(a)sin(b) Remembering to multiply everything by C, we get: 3cos(x) - sin(x) = Csin(x)cos(e) + Ccos(x)sin(e ...
