### Command

- ACOS <n>

- Returns the arc cosine value of the input.
- The commands DEGREES and RADIANS are used to say whether angles are specified in degrees or radians.

### Parameters

- <n>
- Anything that evaluates to a number. This can be a variable, a number, another function, or an expression which includes numbers, variables and/or functions.

- For example:

- 123
- r1
- r2 + r3
- (r1 + (abs(a1 * a2) / (b3 * 62)))

### Example

- a1 = ACOS(r1)

- a1 = ACOS(w1+0.12)

- a1 = ACOS(1/abs(18124.124))
