1) Double Integrals over Rectangular Regions: a. If R = [-2.2]x(0.2). use a Riemann sum with sample points as the upper right corners of each square, and dividing R into 8 squares with m = 4 and n = 2 to estimate the value of If. (4-x + y)4. Please show all work. b. Find the exact volume of this solid region by evaluating the iterated integral JJ (4 x* + >). 3) Set up (but do not evaluate) an integral to find the volume of the solid that is under the surface z = 1 + xy and above the region enclosed by x = >" and x = 4 in the xy-plane . Clearly document your work. Make sure to include your units and include complete sentences where necessary. Please box/highlight your answers. 1) A region R is shown. Decide whether to use polar coordinates or rectangular coordinates and write (), /(x, y) dA as an iterated integral, where f is an arbitrary continuous function on R.
