<p>Why is it that the parameters to the atan2 function are “backwards”? Ie, why does it accepts coordinates in the form <code>y, x</code> instead of the standard <code>x, y</code>?</p>

<p>Because it's similar to <code>atan(y / x)</code>, with <code>y</code> as numerator and <code>x</code> as denominator.</p>

Why are the parameters to `atan2` “backwards”?

Because it's similar to atan(y / x), with y as numerator and x as denominator.
