Find the smallest positive root of the equation `sqrt(sin(1-x))=sqrt(cos"x")`

Explanation

To find the smallest positive root of the equation \( \sqrt{\sin(1-x)} = \sqrt{\cos x} \), we can follow these steps:

### Step 1: Square both sides
Starting with the given equation:
\[ \sqrt{\sin(1-x)} = \sqrt{\cos x} \]
Squaring both sides, we get:
