ArcCot

Returns the inverse cotangent, in radians.

Module: Math

Signature

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

Parameters

Name	Type	Description
x	float64 / float32	Any value.

Returns

HalfPi - ArcTan(x), the angle in (0, Pi) whose cotangent is x, defined for every real x — including 0.0, where ArcCot(0.0) is HalfPi rather than a pole. A NaN argument propagates.

Example

import Math::ArcCot;

let a = ArcCot(0.0); // 1.5707963267948966 (HalfPi)
let b = ArcCot(1.0); // 0.7853981633974483 (QuarterPi)
