Plot functions in C#, Part 3

This is the third example that shows how to plot functions that draw hearts. This time the function is:

The following examples also draw heart-shaped functions. See the first for an explanation of how the programs work.

• Plot a heart-shaped function in C#
• Plot functions in C#

The difference is that this example uses the function shown above. The following code shows how it implements the function in code.

// The function.
private float HeartFunc(float x, float y)
{
    double a = x * x;
    double b = 5.0 * y / 4.0 - Math.Sqrt(Math.Abs(x));
    return (float)(a * a + b * b - 1);
}

See the earlier example for more details.
