Write the least value of `cos^2theta+sec^2thetadot`

Explanation

To find the least value of \( \cos^2 \theta + \sec^2 \theta \), we can follow these steps:

### Step 1: Rewrite the secant function
Recall that \( \sec \theta = \frac{1}{\cos \theta} \). Therefore, we can rewrite \( \sec^2 \theta \) as:
\[ \sec^2 \theta = \frac{1}{\cos^2 \theta} \]
