Step-by-step explanation:

Given

— The expression missing from the question

Solving (a): Write the left hand side in terms of sin and cosine

In trigonometry:

and

So, the expression becomes:

Rewrite as:

Solving (b): Simplify

Change / to *

Solving (c): The property used

To do this, we need to further simplify

Take LCM

Apply quotient identity

This gives

Hence, the properties applied are:
