01

Step 1. Given information.

Consider the given question,

sin195掳路cos75掳

We know localid="1646458669499" role="math" sina路sinb=12sina+b+sina-b.

Using the formula, we get,

sin195掳路cos75掳=12sin195掳+75掳+sin195掳-75掳

02

Step 2. Simplify the equation.

Continuing the above equation,

sin195掳路cos75掳=12sin270掳+sin120掳sin195掳路cos75掳=12-1+32sin195掳路cos75掳=1232-1
