OSISZ. 2 a. (5 pts) Make two graphs of the region bound by y = cos(x) and y = 1 - 2x, for 2 b.(5 pts) Consider the solid of revolution that is formed when the region is rotated about the r-axis. Sketch a typical cylindrical shell for this solid of revolution on the first graph you created in 2 a. 2 c. (10 pts) Set up an integral to compute the volume of the solid of revolution using the method of cylindrical shells. 2 d. (5 pts) When computing the volume of the solid of revolution in 2 b, using the method of discs/washers, we consider cross sections of the solid instead of cylindrical shells. Sketch a typical such cross section for this solid using the second graph you crated in 2 a. 2 e. (10 pts) Set up an integral to compute the volume of the solid of revolution using the method of in discs / washers 2 f. (5 pts) Compute the volume of the solid of revolution using any method you like
