Hmm, I can't seem to get this double integral transformation:(adsbygoogle = window.adsbygoogle || []).push({});

int(limits of integration are 0 to 3) int (limits of int are 0 to x) of (dy dx)/(x^2 + y^2)^(1/2)

and i need to switch it to polar coordinates and then evaluate the polar double integral.

i sketched the region over which i am integrating and it isn't a circular region (which is why I guess this was assigned).

but i cant the limits of integration for the theta angle. the radius goes from 0 to 3, but i cant get the theta angle limits of integration.

the answer is 3ln(sqrt(2) + 1))

i can see where the 3 comes from, but i dont know where i would get the ln term.

thank you in advance
