Logarithmic spirals are also congruent to their own involutes, evolutes, and the pedal curves based on their centers.
2.
A "'fish curve "'is an ellipse negative pedal curve that is shaped like a fish.
3.
Terquem's other contributions to mathematics include naming the pedal curve of another curve, and counting the number of perpendicular lines from a point to an algebraic curve as a function of the degree of the curve.
4.
Then when the curves touch at " R2 " the point corresponding to " P " on the moving plane is " X ", and so the roulette is the pedal curve.
