# tand

Tangent of argument in degrees

## Syntax

``Y = tand(X)``

## Description

example

````Y = tand(X)` returns the tangent of the elements of `X`, which are expressed in degrees.```

## Examples

collapse all

`tand(90)`
```ans = Inf ```
`tan(pi/2)`
```ans = 1.6331e+16 ```

`tand(90)` is infinite, whereas `tan(pi/2)` is large but finite.

```z = [180+i 15+2i 10+3i]; y = tand(z)```
```y = 0.0000 + 0.0175i 0.2676 + 0.0374i 0.1758 + 0.0539i ```

## Input Arguments

collapse all

Angle in degrees, specified as a real-valued or complex-valued scalar, vector, matrix, or N-D array. The `tand` operation is element-wise when `X` is nonscalar.

Data Types: `single` | `double`
Complex Number Support: Yes

## Output Arguments

collapse all

Tangent of angle, returned as a real-valued or complex-valued scalar, vector, matrix, or N-D array of the same size as `X`.
