a) State the principle of comparison for integrals. b) Let f(xy) = sqrt (2+x+y). Plot some level sets of f inside the unit disc x+ys 1, marking the level value for each. Include at least one which is reduced to a single point. c) Using the comparison principle, give an upper bound to Jo f(x,y) dA, where Dis the unit disc (see above).
