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.
