The library is split into several modules, the core and several add-ons. This allows you to load only the functions needed. The core houses the parser and most of the function found the JavaScript Math object. The additional modules are Algebra, Calculus, Solve, and Special.
Parsing is performed with the use of the nerdamer object which takes a string as it's main parameter.
See the Quick start to get up and running quickly. Note that you can now use internal functions through the new API. For example as an alternative to doing:
var x = nerdamer('diff(sin(x)/x, x)');var x = nerdamer.diff('sin(x)/x', 'x');
