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.
