I.e it is given by the complex exponential function. See also the article on atan2 for how to elegantly handle some edge cases So for the element: If in the alternative θ is chosen to run from −90° to +90° in opposite direction the earlier it can be found uniquely from an e but beware an arccotangent In this case in all formulas below all arguments in θ should have sine and cosine exchanged and as derivative also a plus and minus exchanged All divisions by zero result in special cases being directions along one the main axes and are in practice most easily solved by observation. Note that many computer systems may fer a more concise function for computing θ {\displaystyle \theta } such as atan2(y,x) in the C language. Let (x y z) be the standard Cartesian coordinates and (ρ θ φ) the spherical coordinates with θ the angle measured away from the +Z axis (as [1] see conventions in spherical coordinates) As φ has a range 360° the same considerations as in polar (2 dimensional) coordinates apply whenever an gent it is taken θ has a range 180° running from 0° to 180° and does not pose any problem when calculated from an ine but beware for. This is a list some the most commonly used coordinate transformations 2-Dimensional[Edit] Let (x y) be the standard Cartesian coordinates and r and θ the standard polar coordinates.
