cot, coth
2cot, coth
Purpose 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.
2-342
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 – π < x < 0 and
0 < x < π.
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))
