For all `theta` in `[ 0, pi//2]`, show that `cos ( sin theta) gt sin (cos theta)`.

Explanation

To prove that \( \cos(\sin \theta) > \sin(\cos \theta) \) for all \( \theta \) in the interval \( [0, \frac{\pi}{2}] \), we will follow these steps:

### Step 1: Analyze the functions involved
We start by noting the behavior of the functions \( \sin \theta \) and \( \cos \theta \) in the interval \( [0, \frac{\pi}{2}] \). In this interval:
- \( \sin \theta \) increases from 0 to 1.
- \( \cos \theta \) decreases from 1 to 0.

### Step 2: Establish the inequality
