Webatan is tan inverse, that is, gives you the angle given the tan. When you call atan(tan(a+2*pi)), the answer will be a. This will be inadequate for your application. atan2 will take 2 arguments to help this exact situations. atan takes x and y, which are basically cos(a) and sin(a). WebMar 16, 2024 · The Atan2 function returns the arctangent, or inverse tangent, of the specified x and y coordinates as arguments. The arctangent is the angle from the x -axis …
WebPurpose. ATAN2 returns the arc tangent of n1 and n2. The argument n1 can be in an unbounded range and returns a value in the range of - pi to pi, depending on the signs of n1 and n2, expressed in radians. This function takes as arguments any numeric data type or any nonnumeric data type that can be implicitly converted to a numeric data type.
