There are a number of function names and operation symbols that should
be set in normal (roman) type in an expression, such as in
f (θ) = sinθ + log(θ +1) - sinh(θ2 + 1)
and


= 1 .
We know that simply typing $log\theta$
would produce the
incorrect result
logθ
and that using $\mbox{log}\theta$
would leave us having to insert
a little extra space between the log and the θ
logθ .
So LATEX provides a collection of ``log-like functions'' defined
as control sequences. Table
shows those that are
available. Here are some examples of their use:

Notice how LATEX does more than just set an operation like
sup in roman type. It also knew where a subscript to that operator
should go.
