Answer
Here's the proof for the given trigonometric identity:
We need to prove that:
Step 1: Start with the Left Hand Side (LHS) of the equation.
Step 2: Apply double angle identities for and . We use the identities:
Substitute these identities into the LHS:
Step 3: Expand and simplify the numerator. The constant terms and cancel each other out:
Step 4: Factor out from the numerator.
Step 5: Cancel out (assuming ).
This is equal to the Right Hand Side (RHS) of the equation. Therefore, the identity is proven.
