Given the double integral [tex]\int\int_R[/tex] [tex]\sqrt{}x^2+y^2[/tex] dx dy where R is the unit circle.(adsbygoogle = window.adsbygoogle || []).push({});

We are only given the equation for the unit circle but don't we need more equations so I can change the equations to a single variable and then find the Jacobian so how do I find the Jacobian.

How do I find a point interior to R at which the Jacobian vanishes.
