To help you efficiently during Office Hours, I ask that you come prepared.
You should be familiar with the material relevant for the given problem.
I will also ask you to show me your attempts to tackle the difficulty.

As a rule, one cannot learn mathematics by watching somebody else do it.
You have to try hard, realize how the problem relates to what you know,
get some feeling about what does not work, and only then external help can
truly open your eyes.
