c# build dynamic expressions help

[mirhagk]

The name says it. I want to create a function on the go. Basically I want to make a graphing calculator and I want to know how if it's possible to create a lamda or Func<> on the go. (if not I have a worse case scenario of a switch and a list of functions that it will run instead of just one. (ie the functions are single operators)
