Formula

x = r(t - sin(t)); y = r(1 - cos(t)) where t is parameter in radians
  • Cycloid calculates its result from Radius (r), Parameter (t, in radians). It uses the formula x = r(t - sin(t)); y = r(1 - cos(t)) where t is parameter in radians. Change any input to recalculate the result instantly.
  • The main inputs are Radius, Parameter. Enter them in the units and format shown in the calculator.
  • Keep comparable quantities in compatible units whenever the formula combines or compares them.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Cycloid

Inputs
  • Radius: 1
  • Parameter: 3.1415926535898 t, in radians

Using Radius (r) = 1, Parameter (t, in radians) = 3.14159265, the calculated result is 2.
