Quick Reference
The length of the straight line segment obtained by straightening the arc without stretching it. Except where the curve forms part of a known shape, the arc length has to be calculated by integration, and the form depends on the coordinates used:
in Cartesian coordinates:
in polar coordinates: for the length between r=u and r=v or if the integration is carried out for a range of angles, it is in the form
in parameterized form (x(t), y (t) it will be
