ACOS(x)
- Where x is the number and it is varying from -1 to 1.
- The value of ACOS(x) in radians in the range 0 to pi().
- Calci returns the value of arccosine (inverse cosine) in Radians.
- The number can be a single value or any number of values.
For example, ACOS(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 trigonometry.
- Also it is called as Cyclometric function.
- ACOS is described as arcCOS of a given number and denoted by .
- In ACOS(x), x value should be between -1 & 1.
- To find the angle in degrees, multiply the result angle with 180/PI(), or use DEGREES function.
.For example ACOS(0.5)*180/PI() or DEGREES(ACOS(0.5)) gives 60
Examples
ACOS(x)
- x is the number
| ACOS(number) | Angle(radians) |
| ACOS(0) | 1.57079632 |
| ACOS(1) | 0 |
