ATAN(x)
- Where n is the TAN of the angle and is from -1 to 1.
- by default the result obtained will be in radians
- Calci returns the arcTAN (inverse Tan) of a number. Output is the angle in radians.
- To convert arcTAN to the degrees, multiply it by 180/PI.
- 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 tangent in trignometry,and also it is called as cyclometric function.ATAN is described as arctan and denoted by tan-1 (x).In ATAN(x) ,x value appilcable for all real numbers.Here x is in radians. To convert a degree value to radian, multiply 'x' with PI()/180 or use the radians function RADIANS(X)
