LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents. LaTeX is available as free software. Latex has been widely used in the field of physics and mathematics where writing equations is a must. Latex is also available for web and can be used easily. I am also using latex to write equations on this site and wordpress plugin called jetpack come with the latex facility. All you have to do is install Jetpack plugin for wordpress and activate the plugin. That’s it. You are now ready to write beautiful mathematical equations. The aim of this post is to give code of some of the most popular equation that comes up in Math and Physics.
