In polar coordinates it is expressed by the equation "p equals a times 1 plus the cosine of theta," and its area can be found by "1.5 pi a squared."
In polar coordinates it is expressed by the equation "p equals a times 1 plus the cosine of theta," and its area can be found by "1.5 pi a squared." In the point-wise construction of it, let "O" be a fixed point of a circle "C" of diameter "a," and "Q" a variable point of "C."  Lay off distance "a" along the secant "OQ," in both directions from "Q," and the locus of the two points thus obtained is this figure.  Generated by a point of a circle that rolls without slipping on a fixed circle of the same diameter, FTP, name this curve that appears heart-shaped.
