I think your boundaries are correct.

Don't forget about that extra r when using polar integration.

Should the answer be the same as or am I missing the point here?

Or rather, that is R. Which is basically the upper left portion of a doughnut. But what does the area of integration look like?

Pardon me for being the village idiot, but could somebody please answer this one question for me:

When sketching the area of integration, do I just sketch , or do I have to consider ? - Nov 14th 2009, 03:51 AMrn443

yeah I realized that last night. Anyway, I've got the right answer now. Thanks dudes.
