ATAN2
Returns the inverse tangent (the arc tangent) for specified x and y coordinates.
Syntax:
ATAN2(x_coord; y_coord)
- x_coord is the value of the x coordinate.
- y_coord is the value of the y coordinate.
- ATAN2 returns the inverse trigonometric tangent, that is, the angle (in radians) between the x-axis and a line from point x_coord, y_coord to the origin. The angle returned is between -PI and PI.
- To return the angle in degrees, use the DEGREES function.
Example:
ATAN2(20; 20)
- returns 0.785398163397448 (PI/4 radians).
DEGREES(ATAN2(12.3; 12.3))
- returns 45. The tangent of 45 degrees is 1.
