Section 11 Further Reading
Subsection 11.1 Specialized Subdivisions
In a longer work you might wish to have some references on a perchapter basis, or similar. You can make a “references” subdivision anywhere to hold bibliographic items, and you can reference the items like any other item. For example, we can cite the article below [11.4.3, Chapter R], included an indication that a specific chapter may be relevant.
Exercises 11.2 Exercises
1.
No problem here, but the next two are in an “exercise group” with an introduction and a conclusion, along with an optional title. The two problems of the exercise group should be indented some to indicate the grouping.
N.B. An <exercisegroup>
is meant to hold a collection of (short) exercises with common, shared, instructions. Do not use this structure to subdivide an <exercises>
division, as you will eventually be disappointed. Instead, use the available, but under development as of 20191102, <subexercises>
, which requires a <title>
.
Two Derivative Problems.
In the next two problems compute the indicated derivative.
You could “connect” the image above with the exercises following as part of this introduction
for the exercisegroup
.
2.
\(f(x)=x^3\text{,}\) \(\frac{df}{dx}\text{.}\) This sentence is just a bunch of gibberish to check where the second line of the problem begins relative to the first line.
We crossreference the next problem in this exercise group. For the phraseglobal
form, the common element of the crossreference and the target should be the exercises
division, and not the enclosing exercisegroup
: Exercise 3 of Exercises 11.2.
3.
\(y = \cos(x)\text{,}\) \(y^\prime\text{.}\)
Note that the previous two problems used very different notation for the function and the resulting derivative.
4.
This isn't really an exercise, but an explanation that the next <exercisegroup>
has a title and no <introduction>
, which once resulted in some aberrant formatting in LaTeX output.
Two More Derivative Problems.
Some common instructions would go here in the <introduction>
5.
\(f(x)=x^3\text{,}\) \(\frac{df}{dx}\text{.}\) This sentence is just a bunch of gibberish to check where the second line of the problem begins relative to the first line.
We crossreference the next problem in this exercise group. For the phraseglobal
form, the common element of the crossreference and the target should be the exercises
division, and not the enclosing exercisegroup
: Exercise 3 of Exercises 11.2.
6.
\(y = \cos(x)\text{,}\) \(y^\prime\text{.}\)
7.
Compute \(\int 3x^2\,dx\text{.}\)
8.
One of the few things you can place inside of mathematics is a “fillin” blank. We demonstrate a few scenarios here. See details on syntax in Subsection 4.7–the use is identical within mathematics.
Inside inline math (short, space for \(x\)): \(\sin(\fillinmath{x})\)
Inside inline math (default, space for \(XXX\)): \(\sin(\fillinmath{XXX})\)
Inside exponents and subscripts (each is space for the string “12”). In this case, be sure to wrap your exponents and subscripts in braces, as would be good LaTeX practice anyway: \(x^{5+\fillinmath{12}}\,y_{\fillinmath{12}}\)
Inside inline math (too long for this line probably, 40 characters long): \(\tan(\fillinmath{Mxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx})\)

So use inside a displayed equation
\begin{equation*} 16\log\space\fillinmath{1x^2} \end{equation*}like this one.

Inside the second line of a multiline display:
\begin{align*} y &= x^7\,x^8\\ &= x^{\fillinmath{15}} \end{align*} This fillin has the historical
@characters
attribute for a fillin inside math: \(1+\fillinmath{XXXXX}+4=10\text{,}\) which may be more convenient, but may not side properly in places like subscripts, superscripts, fractions, limits of integrals, and so on.

This is not a real exercise, we just want to explain that this is another subsection of exercises, which has two consecutive exercise groups.

Exercise Group.
An <exercisegroup>
can have a cols
attribute taking a value from 2–6. Exercises will progress by row, in so many columns. On a small screen, the HTML exercises may reorganize into fewer columns.

This feature was designed with short “drill” exercises in mind. With long exercises, or exercises with long hints, answers, or solutions, there is a risk that the LaTeX output will have bad page breaks in the vicinity (just before) such an exercise that occupies too much vertical space. Edit, rearrange, or use fewer columns to see if the situation improves.

This is a conclusion, which has not been used very much in this sample. Did you see that the entry for [11.4.3] has a short annotation? So you can make annotated bibliographies easily.
