	Maple ploting, Staple your plots together.

	All plots need to have
	1) Your name as part of the title (add titles with the options like)
	plot3d(sin(x)*sin(y),x=-Pi..Pi,y=-Pi..Pi,
		title=`the Good Doctor plots sin(x)sin(y)`);
	(note the use of backquotes(`) and not quotes(')).
	2) Labeled axises see the label option to plot3d)
	3) rotate the plot to a _good_ point of view.

1. Graph x^2+xy+2y^2+7yz-z^2+3x-xz=1 with axis labeled correctly and 
identify the figure.
2. The curve <cos(e^t),sin(e^t),t> t in [0,5] (this graph has a pretty
picture and the initial graph is not.)
3. ContourPlot of the function (its definition takes two lines)
g(x,y)= 3*(1-x)^2*exp(-x^2-(y+1)^2)
	- 10*(x/5-x^3-y^5)*exp(-x^2-y^2) -(1/3)*exp(-(x+1)^2-y^2)
4. Cylinder co-ordinates r=1+z sin(theta) for z in [0,2]
5. Looking Problem 35 Section 11.6, it follows that the intersection
of the hyperbolic parabolid z=x^2-y^2 and the plane y=x+1 is a straight
line. Graph the two curves together so we can see this line.

Hints implicitplot3d,spacecurve,contourplot,cylinderplot,implicitplot3d
or plot3d. Try using [-3,3] ranges.

The following example will help get 2D contour plots.
f:=(x,y)->x^2+y^2;
L:={seq(f(x,y)=2*i,i=1..9)};
a:=implicitplot(L,x=-3..3,y=-3..3):
