The atan2 function returns the arc tangent of y / x. It will return a value between -π and π. radians = Math.Atan2(y, x) angle = radians *(180 / Math.PI) Console.WriteLine(line1, Environment.NewLine) Console.WriteLine(line2, x, y, radians) Console.WriteLine(line3, angle) End Sub End Class ' 'This example produces the following results: ' 'The tangent of 30 degrees is 0.577350269189626. Convert 4 + 3i into polar coordinates. z = 4 + 3i; r = abs (z) r = 5. theta = atan2 (imag (z),real (z)) theta = 0.6435.

C atan vs atan2

The atan2() function returns the arc tangent of y/x, in the range [-pi, +pi] radians. If both y and x are 0.0, the result is undefined. If in POSIX mode, errno is set to EDOM. If the value of y or x is NaN, NaN is returned.

Remarks. A positive result represents a counterclockwise angle from the x-axis; a negative result represents a clockwise angle. ATAN2(a,b) equals ATAN(b/a), except that a can equal 0 in ATAN2. C++ atan2() function. atan2() function is a library function of cmath header, it is used to find the principal value of the arc tangent of y/x, where y is the proportion of the y-coordinate and x is the proportion of the x-coordinate, it accepts two arguments (y, x) and returns arc tangent of y/x in radians. Syntax of atan2() function: atan2(y, x); There are two functions for calculating the inverse tangent or arctan in Excel.

This function is defined in header file. [Mathematics] tan -1 (y/x) = atan2(y, x) [In C++ Programming] The arc tangent function with two arguments is called as the atan2. It can be represented as atan2(y,x). It was initially used by the computer programming languages and now it has been used in various science and engineering fields. The results of the atan2 function will range between -π to +π. Find the atan 2 value with this calculator.

arctan or atan or tan^-1, and try to visualize the values of their images,. 28 Notice how atan1 has 2 discontinuities, while atan2 has 1  Most maths libraries have a atan2(y,x) function which takes both x and y as The following program shows the difference between atan and atan2 results: 29 Mar 2007 It would be easy enough to implement if I had an atan function, but, alas, I lack that one too. All I have are the "regular" sin, cos and tan. I can't  whereas the atan function computes the arctangent in only two quadrants.
