Hi, can someone please quickly help me check if I've made a correct attempt at the following question. I'm having doubts whether my integral is right or not because I tried integrating it and applying the limits, but I didn't get the given answer 15/8. Can someone help? thank you! http://i26.photobucket.com/albums/c109/mathsnerd/84c1d9ff.jpg I've not included my diagram but I found to limits to be 1 < u < 2 and 1 < v < 2 .
