ADDITIONAL DIRECTIONS FOR HOMEWORK #3
(1) Be sure to distinguish between similar looking symbols: Use < (which is typed as
$<$) for less than but ⟨ (typed as $\langle$) for the symbol that the book uses
for marking sequences. In addition, you should use the command $\colon$ for the
colon in writing a function (as in f ∶ X → Y ), not a regular colon.
(2) use the command usepackage if you want to use special symbols. For example,
the MnSymbol package allows you to make the symbol for products ⨉ (typed as
$\bigtimes$) expandable as in ⨉ Xα or ⨉ Xα . Other useful packages are mathrsfs
α
(for fancy scripts), textcomp (for making the complement symbol ~, typed as \texttildelow,
available).
(3) Use the enumerate, align (or align*), gather (or gather*), cases environments when
appropriate.
(4) Use the equation environment with the \label command to get numbered equations
and to make TEX generate the correct equation numbers in your text.
(5) It is always appropriate to ask me about a TEX command, package, or environment.
