## acos

Calculates the arccosine of a numerical value.

### Syntax

```console
| acos(<number>) as <alias>
```

### Example

The following example returns A with a value of `1.0472`, in radians.

```console
| acos(0.5) as A
```

## asin

Calculates the arcsine of a numerical value.

### Syntax

```console
| asin(<number>) as <alias>
```

### Example

The following example returns A with a value of `0.5236`, in radians.

```console
| asin(0.5) as A
```

## atan

Calculates the arctangent of a numerical value.

### Syntax

```console
| atan(<number>) as <alias>
```

### Example

The above example returns T with a value of `0.7854`, in radians.

```console
| atan(1) as T
```

## cos
