Assuming the curves are smooth the proof of the theorem is trivial: We know from 18.02 that the gradient ruis orthogonal to the level curves of uand the same is true for rvand the level curves of v. Since, by Lemma 5.4, the gradients are orthogonal this implies the curves are orthogonal. Finally, we show that f0(z) 6= 0 means the curves are ...

Titration curves for weak acids, such as HC 2H 3O 2 , show an initial small rise in pH, but then lead into a region where the pH changes only slowly. The solution composition here is a buffer and this part of the titration curve is the buffer region. Eventually the pH climbs very sharply and
