WebMath.atan cannot tell the difference between the first and third quadrants, since the ratio, say, -1/-1 is the same as +1/+1. Nor will Math.atan work well if y=0, since division by 0 is not allowed. But Math.atan2 keeps the x and y arguments separated, so it can tell which quadrant the answer is in, and it can handle the case y=0. WebThe Math.atan2 () method returns the arctangent of the quotient of its arguments, as a numeric value between PI and -PI radians. The number returned represents the counterclockwise angle in radians (not degrees) between the positive X axis and the point (x, y). Note: With atan2 (), the y coordinate is passed as the first argument and the x ... Web1-3) Computes the principal value of the arc tangent of num.
