Cotangent of argument in radians
Y = cot(X)
The cot function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.
Graph the cotangent 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)), grid on
