Function angular_frequency_from_period 

pub fn angular_frequency_from_period(period: f64) -> Option<f64>

Computes angular frequency from period using ω = 2π / T.

Examples

use core::f64::consts::TAU;
use use_oscillation::angular_frequency_from_period;

let angular_frequency = angular_frequency_from_period(1.0).unwrap();

assert!((angular_frequency - TAU).abs() < 1.0e-12);
