 Trisectrix of Maclaurin

The Trisectrix of Maclaurin is a specific mathematical curve that is notable for its property of trisecting angles. In polar coordinates, it can be expressed as a curve defined by the equation: \[ r = a \cdot \theta \] where \( r \) is the distance from the origin, \( \theta \) is the angle in polar coordinates, and \( a \) is a constant.
