# acscd

Inverse cosecant in degrees

## Syntax

• ``Y = acscd(X)``
example

## Description

example

````Y = acscd(X)` returns the inverse cosecant (cosec-1) of the elements of `X` in degrees. The function's domain and range include complex values. For real elements of `X` in the domain [-Inf,1] and [1,Inf], `acscd` returns values in the range [-90,90]. For values of `X` outside this range, `acscd` returns complex values.```

## Examples

collapse all

```x = [20 10 Inf]; y = acscd(x) ```
```y = 2.8660 5.7392 0 ```

The `acscd` operation is element-wise when you pass a vector, matrix, or N-D array.

```acscd(1+i) ```
```ans = 25.9136 -30.4033i ```

## Input Arguments

collapse all

Cosecant of angle, specified as a real-valued or complex-valued scalar, vector, matrix, or N-D array. The `acscd` operation is element-wise when `X` is non-scalar.

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

## Output Arguments

collapse all

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