The Background

A long, long time ago, in a galaxy far, far away, there lived a fine young man unaware of various things about his past, including: All that, however, was about to change.  ``` ```html Three things were about to happen:
  1. he would discover the Force
  2. he would learn how to use a lightsaber, and
  3. he would meet his father.
``` ```html

The Update

Long after this fellow lived, a famous movie was made about his life. The movie was shot in Tunisia. ``` -------------------------------- ### LaTeX cancel Package Example Source: https://guide.pressbooks.com/chapter/add-mathematical-notation Use the 'cancel' package to visually cross out terms in equations, often used to show simplification steps. ```latex x + \cancel{y} = x ``` -------------------------------- ### Interpret EPUB Validation Log Structure Source: https://guide.pressbooks.com/chapter/fix-validation-errors Example of an EPUB validation error report showing metadata and specific error details. ```text Array ( [time] => Mon Dec 10 22:17:33 2018 [user] => tmcgrath [site_url] => https://yourbooktitle.pressbooks.com/wp [blog_id] => 107381 [theme] => Atwood ) **ERROR(RSC-020): /srv/www/pressbooks.com/releas es/20181205114740/web/app/uploads/sites/107381/pressbooks/exports/Test-Book-2-1544480239.epub/OEBPS/chapter-056-your-chapter.html(26,268): ‘http://bit.ly/btb-v092″>http://bit.ly/btb-v092′ is not a valid URL.** Check finished with errors. ``` -------------------------------- ### LaTeX unicode Package Example Source: https://guide.pressbooks.com/chapter/add-mathematical-notation The 'unicode' package supports the use of various Unicode mathematical symbols directly within your LaTeX expressions. ```latex \forall x \in \mathbb{R}, \exists y ``` -------------------------------- ### Use [latexpage] Shortcode for Chapter-Wide LaTeX Rendering Source: https://guide.pressbooks.com/chapter/add-mathematical-notation Place the [latexpage] shortcode at the beginning of a chapter to render all LaTeX syntax within that chapter without requiring individual shortcode delimiters for each expression. This is useful for chapters with extensive mathematical content. ```shortcode [latexpage] At first, we sample $f(x)$ in the $N$ ($N$ is odd) equidistant points around $x^* $: \[ f_k = f(x_k),\: x_k = x^*+kh,\: k=-\frac{N-1}{2},\dots,\frac{N-1}{2} \] where $h$ is some step. Then we interpolate points {$(x_k,f_k)$}} by polynomial \[P_{N-1}(x)=\sum_{j=0}^{N-1}{a_jx^j} \] Its coefficients {${a_j}$}} are found as a solution of system of linear equations: \[ \left\{ P_{N-1}(x_k) = f_k\right\}, k=-\frac{N-1}{2},\dots,\frac{N-1}{2} \] Here are references to existing equations: (\ref{eq:poly}), (\ref{eq:sys}). Here is reference to non-existing equation (\ref{eq:unknown}). ``` -------------------------------- ### Render LaTeX Equations with Pressbooks Shortcode Source: https://guide.pressbooks.com/chapter/use-shortcodes Use the `[equation]` or `[latex]` shortcode to render mathematical expressions using LaTeX syntax.
