Section 11 Further Reading

Subsection 11.1 Specialized Subdivisions

In a longer work you might wish to have some references on a per-chapter 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 [11.2, Chapter R], included an indication that a specific chapter may be relevant.

Subsection 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.

Two Derivative Problems

In the next two problems compute the indicated derivative.

Use a sidebyside element to insert a relevant image, or tabular, or other un-numbered item that does not fit in a sentence.

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 cross-reference the next problem in this exercise group. For the phrase-global form, the common element of the cross-reference 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 output.

Two More Derivative Problems
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 cross-reference the next problem in this exercise group. For the phrase-global form, the common element of the cross-reference 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 “fill-in” 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, 4 characters): \(\sin(\underline{\hspace{1.818181818181818em}})\)

  • Inside inline math (default, 10 characters): \(\sin(\underline{\hspace{4.545454545454546em}})\)

  • Inside exponents and subscripts (2 characters each). In this case, be sure to wrap your exponents and subscripts in braces, as would be good practice anyway: \(x^{5+\underline{\hspace{0.909090909090909em}}}\,y_{\underline{\hspace{0.909090909090909em}}}\)

  • Inside inline math (too long for this line probably, 40 characters long): \(\tan(\underline{\hspace{18.1818181818182em}})\)

  • So use inside a displayed equation

    \begin{equation*} 16\log\space\underline{\hspace{3.636363636363636em}} \end{equation*}

    like this one.

  • Inside the second line of a multi-line display:

    \begin{align*} y &= x^7\,x^8\\ &= x^{\underline{\hspace{1.363636363636364em}}} \end{align*}

Subsection 11.3 More Exercises

1

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

Introduction to first exercise group.

2

Only exercise of first group.

Conclusion to first exercise group.

Introduction to second exercise group.

3

First exercise of second group.

4

Second exercise of second group.

Conclusion to second 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 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 the the second reference above has a short annotation? So you can make annotated bibliographies easily.
