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 heartshaped functions. See the first for an explanation of how the programs work. Plot a heartshaped … Continue reading
Plot functions in C#
This example shows how to plot functions. This example plots a function that represents a heart shape. The earlier example Plot a heartshaped function in C# shows how to draw a relatively complex heartshaped function. Recently I saw a much … Continue reading
See where two conic sections intersect in C#
This example uses techniques demonstrated in several earlier posts to let you see where two conic sections intersect. To use the example, click the left mouse button five times each to select one conic section> Then click the right mouse … Continue reading
