Rederive this equality using power series
5. (a) We showed in class thate- cos() +isin(). where i is the complex number such that #2-1 (or-v-1). Rederive this equality using power series. (b) Use the identity in (a) to show the identities cos(A+B) co( A) cos(B) -sin(A) sin(B) and sin(A + B) = cos(A) sin(B) + sin(A) cos(B).
