Is there something wrong with the following proof (see below)? To me, it seems like the third line should show dPabdt=−∫ba∂∂tJ(x,t)dx Am I missing something obvious?
Answer
If we look at line 2, we have an integral set equal to:
We then must note that J(x,t) is defined as the negative of:
So the last equation on line 2 should be: −∂J(x,t)∂x as opposed to −∂J(x,t)∂t.
