Differentiate the following function `sqrt((a^2-x^2)/(a^2+x^2))`

Explanation

To differentiate the function \( y = \sqrt{\frac{a^2 - x^2}{a^2 + x^2}} \), we will follow these steps:

### Step 1: Rewrite the Function
First, we rewrite the function in a more convenient form for differentiation:
\[ y = \left( \frac{a^2 - x^2}{a^2 + x^2} \right)^{1/2} \]
