| | + | * x & y are coordinates |
| | + | ==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. |
