# Engineering Resource: Web Equation


Documentation, Documentation.  Documentation.

It is always critical to document progress is a log book.  If using an electronic tool like [Evernote](http://www.evernote.com) or a Blog, it can be difficult to document equations or calculations you've made in a project.

Vision Objects has put together a demo tool that allows for [writing your equation in freehand which then uses image recognition to covert into LaTeX code](http://webdemo.visionobjects.com/equation.html).

For convenience, there is a direct link to WolframAlpha to calculate the equation.  A preview of the LaTeX Equation is provided by the open-source [MathJax javascript](http://www.mathjax.org) rendering engine.
