cot (MATLAB Functions)

Cotangent

Syntax

```
Y = cot(X)
```

Description

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

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

Examples

Graph the cotangent 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)), grid on

Definition

The cotangent can be defined as
