ATAN (Number)

This function is the inverse function of TAN in trigonometry.
The value of ATAN(x) is in radians in the range 0 to ${\frac {-\pi }{2}}$ to ${\frac {\pi }{2}}$ .
Calci returns the value of arctangent (inverse tan) in Radians.
The number can be a single value or any number of values.

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 $tan^{-1}(x)$ .
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
