1. Evaluate the integral : e-(r+y)dydx . 2. Evaluate the integral : rydA where D is the region bounded by the graphs of y = VI, y= -0, T = 2 and x = 4. 3. Evaluate the integral : sin(nx3) dady dadydz 4. Evaluate the integral (12 + 12 -2)3/2 where V is the region bounded by the spheres a ty' + 2 = a? and a ty? + 2? =b' where a > b > 0. 5. Find the volume of the region common to the intersecting cylinders a ty- = 9 and 13 + = =9.O Evaluate 1 1 - X Z e - ( x + yz ) dy dx 0 X is o to 1 4 x 2 + y = 1 y = 0 # 1 1 - X 2 1 sides Using the polar coordinates X =r COS O 4 = r sin e 1J 1 = r OLD CI (xy ) (ro ) x 2 + yz = v z .
