The angle of intersection of the curves `x y=a^2` and `x^2-y^2=2a^2` is zero `0o` (b) `45o` (c) `90o` (d) `30o`

Explanation

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

### Step 1: Differentiate the first curve
The first curve is given by:
\[ xy = a^2 \]
To find the slope of the tangent to this curve, we differentiate both sides with respect to \(x\):
