Log-polar coordinates
open-in-new
<p>In <a href="/facts/Mathematics/pxTouaz4">mathematics</a>, log-polar coordinates (or logarithmic polar coordinates) is a <a href="/facts/Coordinate_system/Mtd0q4SP">coordinate system</a> in two dimensions, where a point is identified by two numbers, one for the <a href="/facts/Logarithm/QeXaV97q">logarithm</a> of the distance to a certain point, and one for an <a href="/facts/Angle/gFUTEQYq">angle</a>. Log-polar coordinates are closely connected to <a href="/facts/Polar_coordinates/HBko4YoN">polar coordinates</a>, which are usually used to describe domains in the plane with some sort of <a href="/facts/Rotational_symmetry/bpvJqcnS">rotational symmetry</a>. In areas like <a href="/facts/Harmonic_analysis/CyG5bIPb">harmonic</a> and <a href="/facts/Complex_analysis/hgCoQlH0">complex analysis</a>, the log-polar coordinates are more canonical than polar coordinates. </p>
