MATLAB Function Reference

acot, acoth

Inverse cotangent and inverse hyperbolic cotangent

Syntax

Y = acot(X)
Y = acoth(X)

Description

The acot and acoth functions operate element-wise on arrays. The functions' domains and ranges include complex values. All angles are in radians.

Y = acot(X) returns the inverse cotangent (arccotangent) for each element of X.

Y = acoth(X) returns the inverse hyperbolic cotangent for each element of X.

Examples

Graph the inverse cotangent over the domains and and the inverse hyperbolic cotangent over the domains and

x1 = -2*pi:pi/30:-0.1; x2 = 0.1:pi/30:2*pi;
plot(x1,acot(x1),x2,acot(x2))
x1 = -30:0.1:-1.1; x2 = 1.1:0.1:30; 
plot(x1,acoth(x1),x2,acoth(x2)
