Range and Max Height

On level ground the flight is symmetric:

$$T = \frac{2 v_0 \sin\theta}{g}, \quad R = v_0 \cos\theta \cdot T, \quad H = \frac{(v_0 \sin\theta)^2}{2g}$$

$T$: time in the air, $R$: range, $H$: maximum height.

At the same speed, $30^\circ$ and $60^\circ$ give the same range; $60^\circ$ climbs higher and stays up longer.

Same speed, $30^\circ$ and $60^\circ$: same range R, different maximum height H.
