What do the graphs of the following two equations look like?
[x^2 + y^2  225] *
[x^2 + y^2  10000] *
[(x  45)^2 + (y  35)^2  225] *
[(x + 45)^2 + (y  35)^2  225] = 0
[y + Sqrt(16  x^2)] = 0
To find out, you can use the examples:
This example uses the PlotFunction method from the first of the previous examples in the following calls:


PlotFunction(gr, AddressOf F1, 6, 6, 6, 6, dx, dy)
PlotFunction(gr, AddressOf F2, 6, 6, 6, 6, dx, dy)


Here F1 and F2 are simply functions that return the values of the two functions.
