Each mathematical formula I have used in my blog till now was an image: I wrote them in a Word document using the equation editor by Microsoft (that I like very much), then I captured the screen and saved it as an image, and then I uploaded them in my blog.
In the past, I tried to find a way to write them as text, without succeeding. But it is in fact possible, by using the LaTeX syntax and a few HTML commands.
These are the first “true” mathematical formulae present in this blog. I will use this page to test the LaTeX syntax for mathematical expressions (a handbook is available here). In the table that follows, I present a series of relevant examples of LaTeX syntax. A useful resource for testing out LaTeX instructions is this website.
