Summary
DescriptionArctangent2.svg |
English: Proportional accurate arctangent2-graph plotted with cubic bezier-curves. The atan2(y,x)-function is especially implemented in programming languages. It yelds the angle from the x-axis to any point (x,y). The case x=0 is not depicted. That complies with the asymptotes at y=±π/2. Labels are created with embedded "Computer Modern" font. |

Arctangent2(arctan2)-function atan2(y,x) takes two arguments x and y. It calculates the angle frome the x-axis to the point (x,y). atan2 is usually implemented in programming languages like C++. from Wikimedia Commons plot-range: -4.5 to 4.5 plotted with cubic bezier-curves in several intervalls the bezier-controll-points are calculated to give a very accurate result. symbols in "Computer Modern" (TeX) font embedded created with a plain text editor using GNU/Linux about: http://commons.wikimedia.org/wiki/Image:Arctangent2.svg source: http://commons.wikimedia.org/ rights: GNU Free Documentation license, Creative Commons Attribution ShareAlike license |
