Verily the identity sin 8x cos 3x cos 8x sin 3x sin 5x Cho

Verily the identity. sin 8x cos 3x - cos 8x sin 3x = sin 5x Choose the sequence of steps below that verifies the identity. A. sin 8x cos 3x - cos 8x sin 3x = sin (8x middot 3x) = sin 5x B. sin 8x cos 3x - cos 8x sin 3x = sin (8x + 3x) = sin 5x C. sin 8x cos 3x - cos 8x sin 3x = sin (8x - 3x) = sin 5x

Solution

sinAcosB-cosAsinB=sin(A-B)

sin8xcos3x -cos8xsin3x=sin(8x-3x)

sin8xcos3x -cos8xsin3x=sin(5x)

 Verily the identity. sin 8x cos 3x - cos 8x sin 3x = sin 5x Choose the sequence of steps below that verifies the identity. A. sin 8x cos 3x - cos 8x sin 3x = s
