Insert mathematical formula in Markdown

Since using Markdown, I have been using Markdown + Github to write articles and sort out what I have learned. This article is also done in this way.

However, Markdown features a good free writing, but it takes a lot of effort to encounter mathematical formulas-each time it is written using Latex first (for the online Latex Editor, refer to [1]), and then saved as an image, the img label is used for reference. When there are many formulas, it is a little complicated.

The method in this article uses the html syntax to call the [1] formula generation API to generate a Latex mathematical formula online, saving the trouble of saving the formula as an image. Of course, there are also some drawbacks. Too many formulas may lead to slower page refresh.

Method 1: servers using Google Chart

For example,

The formula is displayed as follows:

The response speed of the Google Chart server is acceptable, but it is said that some complicated Latex formulas may not be parsed (refer to [2]). <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> VcD4KPGgyPgq3vbeotv6jusq508Nmb3Jrb3Not/7O8cb3PC9oMj4KPHA + signature + CjxwcmUgY2xhc3M9 "brush: java;">

For example,

The result is as follows:
