ACOS(x)
- Where x is the angle in radians and it is from -1 to 1.
- By default calci use Radians as angle
- 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, 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 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.
- To find the angle in degrees, multiply the result angle with 180/PI.
- DEGREES function can also be used.
.For example ACOS(-0.8)*180/PI() or DEGREES(ACOS(-0.8)) gives 143.130102
Examples
ACOS(x)
- x is the COS of the angle
| ACOS(x) | Angle(radians) |
| ACOS(0) | 1.57079632 |
| ACOS(1) | 0 |
