Trying to figure out the following integral was done....
Divergence theorem intv(del.F)dv = ints(F.n)ds
The Attempt at a Solution
I have the correct ans from one of my lectures,
ints(uinjsigmaij)ds - intv((partial)d(ui)/(partial)dxj)sigmaij)dv
I think its done by integration by parts but cant seem to get it to work out.
Also how do people get math script in here??
