The rest of Section 3.1 is of so bad quality that I gave up on trying
to understand it. Try again, observing the following principles:
Define a quantity before you use it.
When defining it, explain its significance informally.
Motivate the formulas. Explain how you arrive at these formulas.
(For instance 3.7 is completely mystical. There are roots,
fractions, exponentials, logarithms. Looks totally random to
me. Could not distinguish it from something out of a random
formula generator. Please explain how you arrive at this
formula. If you cannot, then don't bring this formula.)
