It is always critical to document progress is a log book.  If using an electronic tool like Evernote 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.

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 rendering engine.
