Find the angle of projection of a porjectile for which for horizontal range and maximum height are equal.

Explanation

To find the angle of projection of a projectile for which the horizontal range and maximum height are equal, we can follow these steps:

### Step 1: Understand the formulas for range and maximum height
The formulas for the horizontal range \( R \) and maximum height \( H \) of a projectile are given by:
- Range: \( R = \frac{u^2 \sin 2\theta}{g} \)
- Maximum Height: \( H = \frac{u^2 \sin^2 \theta}{2g} \)

Where:
