“We will study trochoids and related curves using the representation of these curves as mapping of the unit circle in the complex plane. Points on the unit circle, or turns, and their uses in representing curves will be introduced and developed. Then we will prove several results which illustrate properties of trochoids. Special attention will be given to rosettes, trochoids which pass through the origin many times and have radial symmetry. Necessary and sufficient conditions for a trochoid to be a rosette are given, and we will define and study the petals of a rosette. Some trochoids exhibit cusps, and we give conditions for cusps and relate our work to existing results about cusps for families of curves which involve the use of generalized discriminants. Examples for most of the results will be given”--Abstract, page iii.
