5. The difference between the Atan function and the ATAN2 function

Summary: Atan and atan2 are all seeking the inverse tangent function, such as: There are two points (x1,y1), and Point (X2,y2); Then the angle calculation method of the slope of these two points is: Floatangle = Atan ((y2-y1)/(X2-X1)); or float angle = atan2 (y2-y1, x2-x1); Atan and Atan2 differences: 1: The method of filling the parameters is not

6. JavaScript atan2 () calculates the angle of the x-axis to a point

Summary: The JavaScript atan2 () method returns the angle from the x-axis to the point (or X, y). This function has two parameters, the first parameter specifies the x-coordinate of the point, the second parameter specifies the Y-coordinate of the point, note the parameter order of the function, and the y-coordinate is passed before the x-coordinate. This article explains the basic syntax and usage examples of atan2 functions. Need to the code farmers can refer to.
