You may want to subclass gamma (the original SymPy version) instead of
Function, so that you keep all the gamma behavior.

How do I solve for undetermined coefficients in equations like:-
eq =a[0]*cos(x) + (a[1] - 1)*sin(x)
solve(eq, a[0], a[1])

hallo everybody,
I've got following script in an .py file:
import sys
from sympy import *
from sympy.parsing.sympy_parser import *
transformations=(standard_transformations + (
implicit_multiplication_application,) + (function_exponentiation,))
param1=parse_expr(sys.argv[1],
It's just the convention I'm most used to. Systems that can be expressed as
A*x = B I usually solve for x, or if A isn't square, the least squares
solution x. In both cases you need A and B in this form. I suppose Ax + B
could seem more natural though.

I think you are missing the transformation that maps ^ to
exponentiation. The -x is really because it thinks it is Not(x), i.e.,
Xor(x, 2).

Oh, of course. B is on the rhs. This is probably more natural to me too.
Should we make a convenience function that does this? I think this use
of jacobian would be lost on most people.

Hi Aaron,
thanks for the quick answer!
Ok. but I already included function_exponentiation. Is there a further
module I have to include?

I think that is just for letting sin**2 x map to sin(x)**2. It must be
a different one that maps ^ to **.

Ok, i did a PHP workaround before posting the Value to sympy
$VarPost=str_replace(^, **, $param1);
Now it works!
Thanks for your help!
I believe that this is an necessary tool to implement py standard to sympy.
