Subsection11.1Specialized 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 [11.2.2, Chapter R], included an indication that a specific chapter may be relevant.
Subsection11.2References
These items are here to test basic formatting of references.
An online, opensource offering.
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.
Subsection11.3Exercises
1
No problem here, but the next two are in an “exercise group” with an introduction and a conclusion. The two problems of the exercise group should be indented some to indicate the grouping.
In the next two problems compute the indicated derivative.
Use a sidebyside element to insert a relevant image, or tabular, or other unnumbered item tht 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 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 11.3.
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
Compute \(\int 3x^2\,dx\text{.}\)
5
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, 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 LaTeX 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 multiline display:
\begin{align*} y &= x^7\,x^8\\ &= x^{\underline{\hspace{1.363636363636364em}}} \end{align*}
Subsection11.4More 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.

\(1+2\)
6
\(3+4+5\)
7
\(5+6\)
8
Add seven to eight.
9

This feature was designed with short “drill” exercises in mind.
