Detailed Description
Example: Archimedean spiral
The Archimedean Spiral is a spiral where all points corresponding to the locations over time of a point moving away from a fixed point with a constant speed along a line which rotates with constant angular velocity. It is defined by the polar equation:
To get cartesian coordinates, it can be solved for and in terms of and . By setting and , it yields to the equation:
with
The tuple is related to the position for and on the curve. and are positive numbers.
To get reasonable interval starting * sizes, and are restricted to .
