Definition of cycloid in English:
A curve (resembling a series of arches) traced by a point on a circle being rolled along a straight line.
- Neile's parabola was the first algebraic curve to have its arc length calculated; only the arc lengths of transcendental curves such as the cycloid and the logarithmic spiral had been calculated before this.
- Many famous mathematicians, including Descartes, have worked on a class of curves called cycloids.
- He defines evolutes and involutes of curves and, after giving some elementary properties, finds the evolutes of the cycloid and of the parabola.
