double integral problem
|
|
|
Hi everyone,
I have trouble in solving a double integral. Could anyone help me?
\int \int_{D} (sqrt(x^{2}+y^{2})) dxdy
the integral area D is : (x-d)^{2}+y^{2}=r^{2}
I can't get the simplist expression
of the double integral. Can anyone give me a hand?
Thanks in advance!

You already asked this in another group. Either post your
question to one group, or post the question simultaneously to
several groups. Otherwise someone may take the trouble of
answering when it's already been answered elsewhere. |
