Question

The sum formula for the sine function is$\sin \left(A+B\right)=\_\_\_\_\_$.

Short answer

The sum formula for the sine function is $\sin \left(A+B\right)=\underline{\sin \left(A\right)\cos \left(B\right)+\cos \left(A\right)\sin \left(B\right)}$.

Step-by-step solution

Step 1. Given information

The given incomplete statement is as follows:

"The sum formula for the sine function is$\sin \left(A+B\right)=\_\_\_\_\_\_$"

Step 2. Fill in the blank.

The sum formula of the sine function is:

$\sin (A+B)=\underline{\sin \left(A\right)\cos \left(B\right)+\cos \left(A\right)\sin (B})$.
