  • Hypotrochoid - Wikipedia
    In geometry, a hypotrochoid is a roulette traced by a point attached to a circle of radius r rolling around the inside of a fixed circle of radius R, where the point is a distance d from the center of the interior circle
  • Hypotrochoid | Desmos
    Hypotrochoid: A hypotrochoid is traced by a point attached to a circle of radius r rolling around the inside of a fixed circle of radius R, where the point is a distance d from the center of the interior circle
  • HYPOTROCHOID - MATHCURVE. COM
    The hypotrochoids are the curves described by a point linked to a circle (C) rolling without slipping internally on a base circle (C0); therefore, they are the curves obtained with a Spirograph with an internal disk
  • Epitrochoids and Hypotrochoids - Durango Bill
    Epitrochoids and Hypotrochoids are members of the Trochoid family They are formed by rolling one circle around another stationary circle, and the specific curve is formed by the path generated by the end of an arm which is fixed to the rolling circle
  • Hypotrochoid vs. Epitrochoid — What’s the Difference?
    What is a hypotrochoid? It's a type of curve generated when a circle rolls inside another fixed, larger circle, with a point on the rolling circle tracing the path
  • Hypotrochoid - from Wolfram MathWorld
    A hypotrochoid is a roulette traced by a point P attached to a circle of radius b rolling around the inside of a fixed circle of radius a, where P is a distance h from the center of the interior circle
  • Hypotrochoid - MacTutor History of Mathematics
    There are four curves which are closely related These are the epicycloid, the epitrochoid, the hypocycloid and the hypotrochoid and they are traced by a point P P on a circle of radius b b which rolls round a fixed circle of radius a a
  • Hypocycles - Virtual Math Museum
    For other sticklengths these curves are called hypotrochoids resp epitrochoids Circle rolling inside a bigger circle, tracing out a rose curve The random dots help to show the rotating plane centered on the contact point of 2 rolling curves
  • Hypotrochoid: Hypocycloid, Contracted and Protracted
    Hypotrochoid Curves are traced by a Point on a gear that rolls around the inside of a fixed gear The shape of the Hypotrochoid Curve depends on the ratio of the gear-teeth
  • Hypotrochoid - XahLee. info
    Hypotrochoid describes a family of curves Hypotrochoid and epitrochoid are roulette of two circles If one circle is inside another, the curve traced are called hypotrochoids Otherwise (one rolls outside another), the curves are called epitrochoids
