Most of this stuff requires calculus, which of course gives exact
results.

A handy shortcut is to do violence to differential equations by
treating them as algebraic expressions. The linear approximation
yeilds acceptably accurate (+/- a few %) results over short spans.

Keep in mind most component tolerances are +/-5%; generating an exact
answer clutters the page with obfuscating differential calculus
expressions. I try to avoid that because it is overly pendactic and
my keyboard doesn't support the necessary symbols. Calculus is best
done with paper and pencil.:-)
