 	The expressions for $$x$$ and $$y$$ are parametric equations for the line that passes through the origin and has the same value for $$x$$ and $$y$$. Explain why this line only goes from 0 to approximately 6.
 
-4.	You will now write the code needed to plot a circle. The line `XYPlotWindow wCircle;` creates the object `wCircle`  for the window that will contain the plot of the circle. Using the code that plotted the segment as inspiration, write the necessary code for your program to graph a circle of radius 3 centered at the origin. Run your program and, if it is necessary, modify the code until you get the right plot. Remember that the circle should be plotted inside the `wCircle` object. Thus, when you invoke the `AddPointToGraph(x,y)`, `Plot` and `show` methods, they should be preceeded by `wCircle`; e.g. `wCircle.show()`.
