    Changing to polar co-ordinates in double integration

    Okay, so I've asked a specific question on this on here before, but I still don't get it. Can someone help explain it to me? I have the exam with it on tomorrow at 2pm

    Hello Chella ...unfortunately this site is for homework help, not full lessons. Do you have any specific examples? The most basic concept is to convert to polar coordinates using the coordinate changes \left(\begin{array}{cc} x \\ y \end{array}\right)\mapsto\left(\begin{array}{cc} r\cos(\theta) \\ r\sin(\theta)\end{array}\right) remembering to adjust the limits of integration in this new coordinate system...also don't forget the Jacobian of this variable change r
