title: Javascript convert Math Notation into MathML notation
body: <p>I'd like to convert expressions like these:</p>
  
  <p>"a*x^2+b*x^2+c+d"... </p>
  
  <p>"log((a*x)/sin(x))"... </p>
  
  <p>"1/x"...</p>
  
  <p>Into MathML using JavaScript. Any suggestions? The closest I found was ASCIIMathML (http://www1.chapman.edu/~jipsen/mathml/asciimath.html) but that's not the notation I'm looking for exactly.</p>
