how does atan2 function work The 4 Quadrant Inverse Tangent atan2 and Other Inverse Trigonometric Functions In this video we discuss the atan2 function and show how this concept can be extended to other inverse
I read the Wikipedia article which states The function atan2 y x is defined as the angle in the Euclidean plane given in radians between the positive x axis and the ray to the Just to answer you question simply arctangent function atan2 y x uses the sign of BOTH parameters to determine the quadrant of the angle in the range PI to PI 180 deg to 180 deg If you want degrees in the range 0 to 360 do this

ATAN2 y x returns the arc tangent of the two numbers x and y It is similar to calculating the arc tangent of y x except that the signs of both arguments are used to determine the quadrant of the result This video describes the difference between atan and atan2 functions We explain how atan2 solves some of the problems associated with atan i e extends th
P atan2 Y X returns the four quadrant inverse tangent tan 1 of Y and X which must be real The atan2 function follows the convention that atan2 x x returns 0 when x is mathematically In computing and mathematics the function atan2 is the 2 argument arctangent By definition theta operatorname atan2 y x is the angle measure in radian s with pi

It took me long time to find a good formula to calculate the confined angle between two 2D vectors for example u v I have found the following formula The ATAN2 function returns the inverse trigonometric tangent of two coordinates Our formula documentation gets straight to the point and comes with thousands of examples
The Math atan2 method measures the counterclockwise angle in radians between the positive x axis and the point x y Note that the arguments to this function pass You must choose which function you need as you pointed out when m dy dx the results are not always the same There are cases when atan2 is preferred and cases where
