ATAN(x)
- by default the result obtained will be in radians
- Calci returns the arcTAN (inverse Tan) 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 arcTAN or inverseTAN values for each element.
Description
Consider x = -0.8 then =ATAN(0.8) gives 0.64350110879
- This function is the inverse function of TAN in trignometry
- Also it is called as Cyclometric function.
- ATAN is described as arctan and denoted by .
- In ATAN(x) ,x value appilcable for all real numbers.
- To find the angle in degrees, multiply the result angle with 180/PI.
- DEGREES function can also be used.
.For example ATAN(-0.8)*180/PI() or DEGREES(ATAN(-0.8)) gives -38.659808
Examples
ATAN(x)
- x is the angle in radians.
| ATAN(x) | Value(Radian) |
| ATAN(0) | 0 |
| ATAN(1) | 0.7853981633974483
|
| ATAN(90) | 1.5596856728972892 |
