# 1.4: Minicourse Skills Page - Content Reuse Practice


This page is for you to practice with transcluded materials in LibreTexts.  Something like this will show up in any transcluded page, so it will be good to understand what it tells you.  You may also want to use Content Reuse to add subsections of source pages to a page, or dynamic figures created with CalcPlot3D, Geogebra Applets, etc.

## Reusing/Transcluding/Mirroring a Subsection of a Source Page

Between the two lines below is an example of a Content Reuse object (note that before you edit the page, this material appears to be part of this page).

### 2. Formatting functions correctly: sin x, cos x, ln x, arctan x, etc.

Consider:  $$cosx, tan(x), sin^2x, lnx$$  vs. $$\cos x, \tan(x), \sin^2x, \ln x$$ yields:

$$cosx, tan(x), sin^2x$$  vs. $$\cos x, \tan(x), \sin^2x$$

As you can see, it’s important to fix the LaTeX codes for all transcendental functions so they appear formatted properly and clearly.  Note that there should be a backslash in front of each function name and there needs to be either a space or a parenthesis or a circumflex ^ immediately after the function name.  Thus “\sinx” will not be understood, but “\sin x”, “\sin(x)”, and “\sin^2x” will all be understood correctly.  Note that the last one is really equivalent to (sin x)^2.

___________________

This example shows how we can pull in a subsection of another page and make it appear to be part of the current page.  Using this approach we could intersperse content from another source with our own examples and subsections.  The benefit of this is that any typos or formatting fixed in the original source page would immediately be updated on our page as well.

1.  It's Your Turn:  Use the Content Reuse feature to insert the Equation Numbering subsection from the LaTeX Formatting Conventions page in the space between the two lines below.

Go to:   Elements > Content Reuse > Sandboxes > your username > 1.3: Minicourse Skills Page - MathJax/LaTeX Formatting Conventions > Equation Numbering

Note that if the Show Title option is checked, then the title of the section will be included in your document, otherwise just the text in that section will appear.

## Transcluding a CalcPlot3D Dynamic Figure

Below is a dynamic figure created using CalcPlot3D.  It is initially placed in its own page in the Simulations and Visualizations page on the Bookshelves.  We can locate it and place a link to it in our page using the Content Reuse option on the Elements menu that displays above when you are editing a page.

2.  It's Your Turn:  Use the Content Reuse feature on the Elements menu to insert another CalcPlot3D figure below.

Go to:   Elements > Content Reuse > click on the + sign in front of Home > click on the + sign in front of Learning Objects > click on the + sign in front of CalcPlot3D Interactive Figures > Then pick a CalcPlot3D image to insert.

Place CalcPlot3D figure here:

## Transcluding a Whole Source Page (without using the Remixer)

You can also use this Content Reuse feature to directly transclude a page/section from a book in the Bookshelves (or somewhere else in Courses).  That is, we don't even need to use the Remixer to do this, although the Remixer will make it a lot easier to transclude a whole series of pages into a book.

Remember that transcluded pages will adjust their chapter and section numbers (in titles, examples, figures, etc.) but will mirror any updates or corrections made to the original pages.  This is ideal whenever you want your page to be the same as a page located elsewhere on LibreTexts and you understand the efficiency of only needing to correct or update the page in one place.

3.  It's Your Turn:  Create a New Page in this "Chapter" naming it 1.5: Linked Page (or whatever you like).  Save the page.  Then edit it and use the Content Reuse feature to transclude a page from a textbook in the Bookshelves.  (Any page will do.)

Steps to accomplish this:

• Look at the bread crumb trail in the blue bar just below the black control bar at the top of this page
• Click on the item at the far right to go up one level to the Textbook Formatting "book".
• Select New in the black control bar at the top. This will create a new page in your version of the Textbook Formatting book.
• Enter a name for this new page, like 1.5: Linked Page, and then select save.
• Then in this new page (1.5: Linked Page), select Edit in the black control bar.  Use the Elements > Content Reuse > click + sign in front of Home > click + sign in front of Bookshelves > navigate to a page you wish to transclude > Select this page.
• Save the new page and view it.  It should appear as it would in the Bookshelves except that its numbering is 1.5 instead of whatever it was there.

4.  It's Your Turn:  Observe how changes to a transcluded page automatically appear on linked pages.

• Edit this page and use the Content Reuse feature to bring a copy of section 1.2 from this Textbook Formatting book into this page in the space between the two lines below. Save.

• Confirm that the contents of the mirrored/transcluded page are just above this line.
• Now go to the Section 1.2 page and make some changes to it and save the modified page.
• Come back here, reload the page, and observe that the modifications will be present here as well!
