Sin

Returns the sine of an angle in radians.

Module: Math

Signature

func Sin(x: float64) -> float64;
func Sin(x: float32) -> float32;

Parameters

Name	Type	Description
x	float64 / float32	An angle, in radians.

Returns

The sine of x, in the range [-1, 1]. Sin(±0.0) is ±0.0, preserving the sign. Sine has no limit at infinity, so Sin(±Inf) is a NaN; a NaN argument also propagates.

Example

import Math::{ HalfPi, Sin };

let a = Sin(HalfPi); // 1.0
let b = Sin(0.0);    // 0.0
