In mathematics, log-polar coordinates (or logarithmic polar coordinates) is a coordinate system in two dimensions, where a point is identified by two numbers, one for the logarithm of the distance to a certain point, and one for an angle.Log-polar coordinates are closely connected to polar coordinates, which are usually used to describe domains in the plane with some sort of rotational symmetry. Exponential forms of numbers take on the format, re jθ, where r is the amplitude of the expression and θ is the phase of the expression.The amplitude r must be expressed in absolute value form.
