Simplify the following trigonometric expression by following the indicated direction sin 0 1 + cos 0 Multiply 7- cos o by 1 + cos 0 sin e 1 + cos 0 1 - cos ' 1+ cos = *cos (Simplify your answer.)
On the last homework, we used the angle sum identity to simplify sin(0+7) and cos(0+t). Simplify the expressions cos(T0) and sin(T0) using the angle sum identities again. Then plot the point (cos(T0), sin(T+ 0)) on the unit circle. Why do your answers from the angle sum identity make sense? (cos(0), sin(0)
