Using the exponential forms of cos and sin given in (3.11a, b), prove the following

Question:

Using the exponential forms of cos θ and sin θ given in (3.11a, b), prove the following trigonometric identities:

(a) sin(a + B) = sin a cos + cos a sin (b) sin0 = sin 0 -sin 30

Data from 3.11a and b

Cos = eje + e-je 2 (3.11a)

sin 0 = eje- e-je 2j (3.11b)
