Establish the identity. sin (1 - 0) = sin e Choose the sequence of steps below that verifies the identity O A. sin (1 - 0) = cos i cos 0+ sin a sin 0 = (0) cos 0 - (0) sin 0= sino O B. sin (1 - 0) = cos i cos 0- sin i sin 0=(-1) cos 0 + (0) sin = sin e O c. sin (1-0) = sin it cos 0+ cos i sin 0 = (0) cos 0+ (-1) sin 0= sino OD. sin (1 - 0) = sin a cos 0 - cos a sin 0 = (0) cos 0-(-1) sin = sino

Establish the identity. sin zim (3-0)-c cos e Choose the sequence of steps below that verifies the identity OA. JU TU sin sin 2 cos 0 + cos sin e= (1) cos 0+ (0) sin e = cos 0 OB. WE sin BIN = sin cos - cos 2 NT sin 0=(1) cos 0 -(0) sin e = cos 0 OC. sin COS RIN cos - sin sin e = (1) cos 0 + (1) sin e- cos D. sin COS cos e sin RI NI sin e = (0) cos 0 - (1) sin 8 = cos 0
