plot() handles color names for RGB color codes. SymPy document doesn’t explain it clearly or sample codes don’t exit. Here is another example.

I spent few hours to figure out how to apply the chain rule manually to find derivative of a function due to poor documentation of SymPy. I’m not that smart guy.
In IPython-notebook on the web browser interface, checking value of expression is simply typing the name of expression in the following line.
