Detailed Description

Example: Cartesian Heart

There are many mathematical curves that produce heart shapes. With a good solving effort, coordinates of a filled heart shape can be computed by solving the cartesian equation:

\[ x^2+2\left(y-p\times\operatorname{abs}(x)^{\frac{1}{q}}\right)^2 = 1 \]

By setting $p=0.5$ and $q=2$, it yields to the equation:

\[ x^2+2\left(y-\frac{\operatorname{abs}(x)^{\frac{1}{2}}}{2}\right)^2 = 1 \]

To get reasonable interval starting sizes, $x$ and $y$ are restricted to $[-20;20]$.
