Inserting equations into web pages can be accomplished using LaTeX or by saving equations as images. For LaTeX integration, users need to ensure their web server supports LaTeX capabilities, which may require technical assistance from technology forums. If LaTeX is not an option, equations can be rendered as images and embedded in HTML, although this method is less desirable. A specific resource was mentioned for adding LaTeX rendering using PHP, which can facilitate the process for those looking to implement it on their own sites. The discussion also referenced a link that provides guidance on inserting equations on a specific platform.
