As we know that: Cos (a+b) = cosa × cosb – sinxa × sinb. Sin (a+b) = sina × cosb + sina × cosb. Now, we will be substituting these formulas into the equation. [cosx × cosy – sinx × siny) × cosy + (sinx × cosy + cosx × siny) × siny. Now expand the brackets. The graph of y = cos θ. The graph of \(y = \cos{\theta}\) has a maximum value of 1 and a minimum value of -1.

Two, a rotation of angle T followed by one of angle U is the same as a 1.
