What does epicycloid mean?
An epicycloid is a type of curve that is generated by the motion of a point on the circumference of a circle that rolls on the outside of a fixed circle. This curve has been studied in mathematics for centuries and has numerous applications in engineering and design. The epicycloid is characterized by its distinctive shape, which is formed by the rolling motion of the circle. It is often used in the design of gears, mechanical systems, and other devices that require precise motion. The study of epicycloids has contributed significantly to our understanding of curves and their properties.
nounA curve generated by the motion of a point on the circumference of a circle that rolls on the outside of a fixed circle.
- A curve generated by the motion of a point on the circumference of a circle that rolls on the outside of a fixed circle.
- In particular, a curve traced by a point on the circumference of a circle as it rolls around the outside of another circle.
"The epicycloid is a type of curve that has been studied in mathematics for centuries."
"The mathematician spent years studying the properties of the epicycloid."
"The epicycloid can be seen in the design of certain types of gears and mechanical systems."
The plural form 'epicycloids' is used to refer to multiple curves of this type.

Etymology of epicycloid
The term 'epicycloid' originates from the Greek words 'epi', meaning 'upon', and 'kyklos', meaning 'circle'. It is related to the concept of an epicycle, which is a circle that rolls on the outside of a fixed circle. The epicycloid has been studied by mathematicians since ancient times and has numerous applications in engineering and design.
Usage notes
