I am trying to build a rule for manual integration. I want to test
whether an expression matches the general form:
c (e + f x)**p
where c, f, and p can be non-zero expressions not containing x, whereas
e can be zero but again cannot contain x.
Moreover, if the expressions matches the above
Looks neat. I will have to delve into it more. Thanks!

You may want to look at my geometric algebra module that uses sympy
(github.com/brombo/galgebra) and see if it does what you want it to.
I have attached the manual (galgebra.pdf) for you to look at.
I like that :-) That's probably actually all I need for this case

Neat. I'll be monitoring to see when the PR is merged!

Not to hijack this post, but why does subs(phi(z,t).diff(z),...) work
when phi(z,t).diff(t,2) does not contain any derivatives of phi with
respect to z? It seems like this substitution is saying that
phi(z,t).diff(z) = phi(z,t)
I'm new to sympy, so I apologize if this is a stupid question.
I realized that what I wrote here is nonsensical. I can't commute
partial / partial_u through the gradient operator! Silly me

Hi all, I have the following problem. I am trying to set-up the Jacobian

I need to compute some partial derivatives like the one below:
In order to evaluate this I need sympy to be able to do the following
