A little nitpicking, I change x^2 to xsin(x), then to xMath.sin(x), then x*math.sin(x) to no avail. In wxmaxima you just have an iterative notebook and you have available a lot of symbolic and numeric computations with no fuss. Also you can create section, subsections, convert to pdf and html, save in xml, and much more. What is missing in wxmaxima is a tool to use your mouse in a much more dynamic way.
