A plot of the surface z = 3-y^2/4 - x/2 over the region R in the xy plane consisting of all points (x,y,,0) WITH (x,y) inside the 2D circle x^2 + y^2 = 4. come up with a counterclockwise parametrization { x(t), y(t 0} of the circle x^2 +y^2 = 4. use your parametrization and the Gauss green formula to measure by hand calculation the volume of the solid whose top skin is the plotted surface and whose bottom skin is the rectangle R. Provide a minimum of two scholarly references
