Function nikisas::cot

pub fn cot(x: f32) -> f32

Computes the cotangent of a number in radians.

Notes

The input domain is limited to approximately [-2.1e+9, 2.1e+9] due to implementation details (see tan).

Examples

use nikisas::{cot, consts::PI};
assert_eq!(cot(0.25 * PI), 1.0);

Implementations details

It is simply computed as 1 / tan(x) using tan routine.
