If you want to convert the arctangent in degrees, multiply the result by 180/PI.
 
Calci returns the arctangent of the particular x- and y-coordinates. It is the angle from the x-axis to a line with origin (0, 0) and with coordinates (xn, yn).

ATAN2(x,y)


  • x & y are coordinates

Description

  • This function gives the inverse function of Tangent in trigonometry with two arguments (x,y).
  • Here the arguments & .
  • Also ATan2(x,y) is the angle between the x-axis and the point given by the co-ordinate (x,y) on it.
  • Where x is the x-coordinate point & y is the y-coordinate point.
  • The angle is positive for counter-clockwise angles (upper half-plane, y > 0), and negative for clockwise angles (lower half-plane, y < 0).
  • Also the angle is with in to
  • To find the angle in degrees, multiply the result angle with 180/PI().DEGREES function can also be used.
