Google Docs and MathML, first MathML Editor integrated with Google Docs.
The Add-in is a professional 'Mathematics Editor' used to build equations and insert the images into documents. The user can easily add variables, constants, operators, fractions, exponents, logarithms, limits, integrals, derivatives and matrix. Also, the Editor has a built in Wizard to build complex equation.
Because of restrictions to use 'sidebar architecture' in Google Docs, I created a vertical layout for my 'FMath Editor' to be inserted in working page.
let me know what you think.
