To complete the identity of sin u cos v, we can use the trigonometric identity:

sin(A + B) = sin A cos B + cos A sin B

By comparing this identity to sin u cos v, we can see that the expression that completes the identity is sin(u + v).

Therefore, the expression that completes the identity of sin u cos v is sin(u + v).
