WebSep 25, 2024 · 1. ATAN () Function : ATAN () function in MySQL is used to return the arc tangent of any number x. The arctangent of x is defined as the inverse tangent function of x when x is real (x∈ℝ). When the tangent of y is equal to x : tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y : WebDescription. atan returns the angle whose trigonometric arctangent is y x or y_over_x, depending on which overload is invoked. In the first overload, the signs of y and x are used to determine the quadrant that the angle lies in. The values returned by atan in this case are in the range − π π. Results are undefined if x is zero.
