The easiest way to include Latex-based math notation in Evernote is to generate an image from the Latex code using some tool like LaTeXiT and paste the image in Evernote. However, it cannot record the Latex code in place like by MathJax so that it can be modified later. Is there any way to include MathJax or similar function in Evernote, like in Wikipedia or Stack Exchange?
