ATAN(x)
- Where x 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
- Also called as Cyclometric function.
- ATAN is described as arctan and denoted by .
- In ATAN(x) ,x value appilcable for all real numbers.Here x is in radians.
