This isn't for homework but the question fits the general HW format. Basically, I am getting a different answer from my colleague on the double integral below so I am trying to find out why. I am trying to put this into excel so I can play with the numbers and see the different results. The double integral is attached (Image upload wasn't working, hopefully this isn't a big deal).
The values I am using are as follows:
The Attempt at a Solution
So the first integration (with respect to y) yields me this:
Remember, I am putting this through excel so I am keeping the variables in there until the end. The second integration (with respect to x now) yields me this:
So now that I have this, I can have excel plug in the variables listed in the above section and get the answer. With the variables above, I am getting ~2.234. My colleague, however, is getting ~2.361. I do not have access to his work, and he seems confident in his answer. Basically I am bringing up this issue a couple years after he did the original problems and he isn't allotted any more time to work on this so I'm on my own. Is there something I am doing wrong?
