[sympy] Re: Guiding Sympy though trig substitutions

ALSO -- Fu, et al., have already thought a lot about trig simplification and if you just run fu(expr) you may get what you are looking for: >>> ok = fu(P.expand()); print filldedent(ok) D**2 + 2*D*F*sin(x) + 2*D*G*cos(x) + 2*D*H*sin(2*x) + 2*D*J*cos(2*x) + F**2*(-cos(2*x)/2 + 1/2) + F*G*sin(2*x)

[sympy] Re: Guiding Sympy though trig substitutions

Regarding the naming of the Fu transformations -- in keeping with the paper (and anyone else who uses the Fu method) I think it wise to leave the names alone. This doesn't preclude the use of aliases, however, and anyone doing this work can easily write their own aliases. And don't forget to re

Re: [sympy] Multiple dispatch

My guess is that Mul and Add will always just create Add and Mul objects. Other functions will then be used to perform various simplifications on these lists. This is how sets work with Union and Intersection. You call Union(a, b, c, d) where a, b, c, d are all sets. This makes a Union object co

Re: [sympy] Multiple dispatch

SymPy already has a pretty widely used single dispatch system (the _eval_* methods). Multiple dispatch would be useful for any operation that has more than one argument. I hardly have to convince you of the advantage of this approach. The challenge is operations like Add and Mul that take an arbit

[sympy] Multiple dispatch

I've recently become interested in multiple dispatch. I know that this has been a topic of conversation before. Can anyone point me to relevant threads? I've gone through the recent PR by @Upapjojr https://github.com/sympy/sympy/pull/2680 . In particular: 1. What are the strong use cases for

[sympy] Re: GSoC 2014 - Efficient Groebner bases and their applications

Thanks for the hint mario. I could find the source already implemented. Could you please clarify me the following questions too. 1. If the F4 is to be implemented should it use the *F5 algorithm* as well to assist in computing the Groebner basis? 2. From the *efficiency* point of view the F4 ov

Re: [sympy] Re: Electrodynamics in Physics Module

Hello Alan, I don't understand what you mean. I mean to say, sympy must be able to symbolically convert a surface integral into volume integral(vice versa) using divergence theorem(line integral to area integral using stokes theorem). In this case, I'm talking about prasoon's vector module. Using
