Assignment:
Q1 Find the area of the part of the surface 2z = x^2 that lies directly above the triangle in the xy-plane with the vertices at (0,0),(1,0) and (1,1).
Q2. Find the volume of the region in the first octant that is bounded by the hyperbolic cylinders xy = 1, xy = 9, xz = 4, yz = 1, and yz = 16. Use the transformation u = xy, v = xz, w = yz. Note that uvw = x²y²z².
Provide complete and step by step solution for the question and show calculations and use formulas.
