ATAN (Number)
- is any value.
- ATAN() returns the arctangent of a number.
is any value.
Description
- This function is the inverse function of TAN in trigonometry.
- The value of ATAN(x) is in radians in the range 0 to to .
- Calci returns the value of arctangent (inverse tan) in Radians.
- The number can be a single value or any number of values.
to 
.For example, ATAN(0.5,(-0.2),1) gives the arcTAN or inverseTAN values for each element.
- Consider x = 0.8 then =ATAN(0.8) gives 0.67474094
- It is also known as Cyclometric function.
- ATAN is described as arctan of a given number and denoted by .
- In ATAN(x), x value applicable for all real numbers.
- To find the angle in degrees, multiply the result angle with 180/PI(), or use DEGREES function.
.For example ATAN(-0.8)*180/PI() or DEGREES(ATAN(-0.8)) gives -38.659808
Examples
ATAN(x)
- x is the number.
| ATAN(number) | Angle(radian) |
| ATAN(0) | 0 |
| ATAN(1) | 0.78539816 |
| ATAN(90) | 1.55968567 |
