==Description==
 +
*This function gives the inverse function of Tangent  in trigonometry with two arguments (x,y).
 +
*Here the arguments <math>x\neq 0</math> & <math>y\neq 0</math>.
 +
*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 <math>-\pi</math> to <math>\pi</math>
 +
*To find the angle in degrees, multiply the result angle with 180/PI().DEGREES function can also be used.

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.
