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 x & y not both equal to zero.
  • 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 -pi() <angle>=+pi()

Examples

IMCOS(iz)

  • iz is the complex number.
IMCOS(iz) Value(Radian)
IMCOS("2+3i") -4.189-i9.109
IMCOS("2-3i") 4.189-i9.109
IMCOS("2") 0.4161468

Where xn is the x-coordinate and yn is the y-coordinate of that particular point ATAN2 returns the error value when both xn and yn are 0. 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).
