Work out the outward flux of the field across the boundary of the volumetric region bounded bty and . Verify your result using divergence theorem.
that's the question. i tried solve like this;
hence volume part of divergence theorem becomes;
where our volumetric region is
after this i couldn't understand, which coordinate system should i work and what should i write as bounds of integrals.
as i look to surface part of the divergence theorem, i used these substitutions;
these substitutions didn't give me an answer so i need help on both sides of divergence theory.
edit: btw, sorry for grammer mistakes if there is any. my english grammer knowledge isn't good at all.
