Find the angle of intersection of the curves y`=4-x^(2)` and `y=x^(2)`

Explanation

To find the angle of intersection of the curves \( y = 4 - x^2 \) and \( y = x^2 \), we will follow these steps:

### Step 1: Find the derivatives of the curves
The first curve is \( y = x^2 \).
- The derivative \( \frac{dy}{dx} \) for this curve is:
\[ \frac{dy}{dx} = 2x \]
