1 2 {{alias}}( x ) 3 Computes the inverse hyperbolic cotangent of a number. 4 5 The domain of the inverse hyperbolic cotangent is the union of the intervals 6 (-inf,-1] and [1,inf). 7 8 If provided a value on the open interval (-1,1), the function returns `NaN`. 9 10 Parameters 11 ---------- 12 x: number 13 Input value. 14 15 Returns 16 ------- 17 y: number 18 Inverse hyperbolic cotangent (in radians). 19 20 Examples 21 -------- 22 > var y = {{alias}}( 2.0 ) 23 ~0.5493 24 > y = {{alias}}( 0.0 ) 25 NaN 26 > y = {{alias}}( 0.5 ) 27 NaN 28 > y = {{alias}}( 1.0 ) 29 Infinity 30 > y = {{alias}}( NaN ) 31 NaN 32 33 See Also 34 -------- 35
