title: Using caret as exponent in Javascript
body: <p>I am trying to create a simple graphing calculator where a user enters a function of f (like f(x) = x^2+2x+6). Basically the javascript replaces the x in the function with some number and then evaluates the function using eval(). The problem is, I want users to be able to type x^2 instead of default javascript which would be Math.pow(x,2). I'm guessing it's going to be some regular expression but I have little experience with them and find them really confusing, personally. Is it possible to convert a statement like x^3-x^2 to Math.pow(x,3)-Math.pow(x,2) ??</p>
  
  <p>Help greatly appreciated.</p>
