Cycloid polar equation
WebMar 9, 2024 · There are two main polar equations for cardioids depending on whether the cardioid is horizontal or vertical. These two cardioid equations are shown below, where {eq}a {/eq} is a positive constant. Web1. Parametric equations for the cycloid. A cycloid is the curve traced by a point on a circle as it rolls along a straight line. NM = ON A moving point on the circle goes from O(0,0) to M(x,y). It describes the arc NM of length equal to a θ . The coordinates x and y of the point M are: x = ON - MH = aθ - a sin θ y = CN - CH = a - a cos θ so the parametric …
