![]() ![]() Note that it may not be necessary to use LaTeX for an expression or equation. To show an equation in this way, simply write it on its own line and center it using Shift Alt C or the “Align center” button on the visual editor toolbar. You can also show this equation on its own line and centered, as in the following example: These shortcodes can be used to write in-line LaTeX expressions (i.e., in the middle of regular text) or to left-align a LaTeX expression written on its own line.įor example, we all know that a^2 b^2=c^2 is the Pythagorean theorem. This is the simplest and best way in Pressbooks to write LaTeX expressions that will be rendered by MathJax. Use the delimiters … to mark the boundaries between LaTeX and regular text. How to Use LaTeX to Write Expressions in Pressbooks LaTeX Questions Answered in the BCcampus Open Education Pressbooks Guide, the source for the chapter you are reading now, includes more detailed information and answers to frequently asked questions.The LaTeX Project is the website of the team that maintains and develops LaTeX.Whether you are new to LaTeX, familiar with it, or already proficient, the following resources might be helpful to you: In this chapter, you will learn how to get started using LaTeX in Pressbooks. Use the formula V=\pi r^2h to calculate the volume of a cylinder. This example is simple, but LaTeX can be used to write much more complex expressions. It can be used to create documents from scratch or display equations in a web browser with the help of plugins, as is the case in Pressbooks.īelow is an example of what LaTeX can look like. LaTeX is a markup language and typesetting system commonly used in mathematical and scientific writing. This is usually a better way, since it also shows the itex or tex tags, and the text around them, but it doesn't work in locked threads, or when the LaTeX image is in a quote box.Adding Media, Interactivity, and Mathematical Equations 14 Using LaTeX in Pressbooks Move the mouse pointer over the image, and right-click before the larger image appears.Īnother way to see the LaTeX source code is of course to just click the QUOTE button next to the post. So if you want to change it back, you have to be fast. However, this will also make it harder to right-click to bring up the menu, because a right-click on the larger image does nothing. ![]() ![]() If you change the zoom trigger to "hover", you will only have to hold the mouse pointer over the LaTeX image for the larger version to appear. change what you have to do to make the larger image appear. always scale all LaTeX images to a larger or smaller size.change the factor by which the larger image is larger than the default size.\text A right-click will display a menu where you can choose to Note: The blackboard bold font only works with capital letters.įrequently used symbols: This is a list of some of the most useful symbols and their LaTeX codes: Give the results \mathbb A, \mathcal A, \mathfrak A, \mathsf A, \mathrm A, \mathbf A and \mathtt A respectively. The math looks fine to everyone else, but you will need to refresh the page (in your browser) to see the math again. If you often write long pieces of LaTeX code, you may want to start to routinely type extra spaces that will be ignored by the LaTeX processor, for example before equality signs and LaTeX commands that aren't arguments of other LaTeX commands.Īnother bug is that if you edit a post that contains LaTeX code without going to advanced edit mode, the code will not be parsed when you view the thread immediately after saving the changes. To prevent this from happening, you will have to make sure that your code contains a space at least once every 50 characters. This will break the code unless you're lucky enough to have the space end up before a LaTeX command rather than in the middle of it. If you type more than 50 characters without a space, vBulletin will insert one for you after the 50th character. Important bug: vBulletin (the forum software) has a feature that will sometimes break correct LaTeX code. Let f:\mathbb R\rightarrow\mathbb R be the function defined byį(x)=x^2, for all x\in\mathbb R. ![]()
