Hyperbolic cotangent


Y = coth(X)


The coth function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

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

Graph of Hyperbolic Cotangent

Plot the hyperbolic cotangent over the domain $-\pi < x < 0$ and $0 < x < \pi.$

x1 = -pi+0.01:0.01:-0.01;
x2 = 0.01:0.01:pi-0.01;
plot(x1,coth(x1),x2,coth(x2)), grid on
