You can put this solution on YOUR website! sin(x + y) - sin(x - y) = 2cos(x)sin(y) sin(x)cos(y) + cos(x)sin(y) - (sin(x)cos(y) - cos(x)sin(y)) = 2cos(x)sin(y) sin(x

cos (x -y) = cosx ·cosy + sinx ·siny. sin (x +y) = sinx ·cosy sin x ± sin y = 2 cos (x ±y/2)· cos (x-+y/2). cos x ± cosy = -2 sin (x±y/2)· sin (x-+y/2). 1 + cos 2x = 2 cos2

Rewrite as -3cos(2π[x. +2]). • Amplitude = 3. • Curve is flipped over the x-axis. • Period is 2π/b = 2π/2π = 1. Tjena!

Cos (x + y) × cos y + sin (x + y) × sin y = cos x. Firstly, we will be using the trigonometric identities. sin = y.

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..
