ACOS(x)
- Where x is the COS of the angle and is from -1 to 1.
- By default the result obtained will be in Radians
- Calci returns the arcCOS (inverse Cos) of a number. Output is the angle in radians.
- The number can be a single value or any number of values.
For example, ASIN(0.5,(-0.2),1) gives the arcCOS or inverseCOS values for each element.
Description
Consider x = -0.8 then =ACOS(0.8) gives 0.64350110879
- This function is the inverse function of COS in trignometry.
- Also it is called as Cyclometric function.
- ACOS is described as arcCOS and denoted by .
- In ACOS(x), x value should be with in -1 & 1.
.| Number | ACOS |
|---|---|
| 0.8 | 0.64350110879 |
| -0.22 | 1.792610797291 |
| 0.2 | 1.567305661202 |
Examples
ACOS(x)
- x is the COS of the angle
| ACOS(x) | Value |
| ACOS(0) | 1.5707963267948966 |
| ACOS(1) | 0 |
