math logarithmic spiral equation. In mathematics the logarithm is the inverse function to exponentiationThat means the logarithm of a given number x is the exponent to which another fixed number the base b must be raised to produce that number xIn the simplest case the logarithm counts the number of occurrences of the same factor in repeated multiplication. The logarithmic spiral is a spiral whose polar equation is given by raebtheta 1 where r is the distance from the origin theta is the angle from the x-axis and a and b are arbitrary constants.

Polar Coordinates and Logarithmic Spirals Date. The logarithmic spiral can be distinguished from the Archimedean spiral by the fact that the distances. Equivalently the equation may be given by log rA cot.
