cot, coth (MATLAB Function Reference)

Cotangent and hyperbolic cotangent

Syntax

Y = cot(X)
Y = coth(X)

Description

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

Y = cot(X)

returns the cotangent for each element of X.

Y = coth(X)

returns the hyperbolic cotangent for each element of X.

Examples

Graph the cotangent and hyperbolic cotangent over the domains

and

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