Integral form of the Burger's equation
 
Hi, Can someone tell me what the integral form of the inviscid Burger's equation is? I know the differential form. Confused on how to write the integral form of the u(du/dx) term.
Thanks!

1d case:
du/dt + d (u^2/2)/dx =0 --> Int (du/dt) dx + [u^2|x+dx/2 - u^2|x-dx/2 ]/2 = 0
