To prove: The identity

Explanation of Solution
Given information:
The given identity is
Formula used:
Identity:
Reciprocal identity:
Proof:
To prove the identity, take left side of the identity and simplify it.
Further simplify the equation.
From the above, it is clear that the left hand side of the identity is equal to the right side of the identity.
Hence, proved.
