We are asked to simplify the expression:

one divided by cotangent of theta to the second power+ sec θ cos θ

i.e. mathematically it is written as:

We know that:

Hence, we can write this expression as:

Also, we know that:

Hence, we have:

Hence, we get:

Also, we know that:

Hence, we get the simplified expression as:
