# About This Book

**Changes From Adapted Resource**

Overall significant work was done on this version of the text to improve the accessibility and format from the import from Open Stax and other resources.

All mathematical notation was written in LaTeX to allow for MathJax functionality. MathJax provides the following accessibility features:

- Automatic magnification on hover
- Text-to-speech options
- Collapsible math
- Highlight, foreground, and background customization
- The ability to translate math into other syntaxes
- MathJax options in over 20 languages

See the full extent of MathJax’s accessibility features in their documentation.

In addition the following formatting changes were made:

- The majority of images that included math where replaced with LaTeX
- Images were recolored for contrast
- Examples were reformatted into steps for ease of understanding
