Re: [sympy] given a plane equation to extract the coefficients a,b,c,d
Thanks for your prompt response. Really this is a very simple question. Consider a plain algebra equation on 'graph paper'. Sympy.plot(...) allows for a number of key/value pairs for stuff like xticks, etc. However, there is no keyword to on a grid for the resulting plot.

[sympy] Grid in sympy plotting
Greetings: I want to display a grid in a sympy plot. The sympy.doc page only discusses mesh grids. On searching through Google, I found only one result that suggested using matplotlib.pyplot in addition to the sympy.plot(...) method. This should be simple and I am surprised that it is not asked more. Thanks in advance, lee -- You received this message because you are subscribed to the Google Groups "sympy" group.

Re: [sympy] Parse Latex doesn't understand '\sqrt[a]{b}'
The latex parsing is still pretty new. It should not be hard to add support for this. Please open an issue on the issue tracker.
