Function angular_velocity 

pub fn angular_velocity(angular_displacement: f64, time: f64) -> Option<f64>

Computes angular velocity using ω = Δθ / t.

Returns None when time is less than or equal to zero, when any input is not finite, or when the computed angular velocity is not finite.

Examples

use use_rotation::angular_velocity;

assert_eq!(angular_velocity(10.0, 2.0), Some(5.0));
