Where the two surfaces intersect z = x2 y2 = 8 − x2 − y2 So, 2x2 2y2 = 8 or x2 y2 = 4 = z, this is the curve at the intersection of the two surfaces Therefore, the boundary of projected region R in the x − y plane is given by the circle x2 y2 = 4 So R can be treated as a y simple region in the 1 2For example, for g(x,y,z) = z−x2−y2 = 0, we have the graph z = x2 y2 of the function f(x,y) = x2 y2 which is a paraboloid Note however that most surfaces of the form g(x,y,z) = c can not be written as graphs The sphere is an example, where we need two graphs to cover it3D Surface Plotter An online tool to create 3D plots of surfaces This demo allows you to enter a mathematical expression in terms of x and y When you hit the calculate button, the demo will calculate the value of the expression over the x and y ranges provided and then plot the result as a surface The graph can be zoomed in by scrolling
