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])
[{a₀: (-a₁ + 1)⋅tan(x)}]
I would like to get a[0] = 0 and a[1] = 1 as solutions.
Solve works well when terms in 'x' are algebraic expressions however not
for transce
I think that it is reasonable for the first couple lines of any sympy
function foo to be
def foo(expr, ...):
if hasattr(expr, '_eval_foo'):
return expr._eval_foo()
This would work well for trigsimp

Here are some comments on sets in CAS

I think that if you want to deal with subsets of the real numbers you
should look
at the literature from interval arithmetic to see how you can get your

After shifting tan(x) by pi/2, it finds the series of tan(x - pi/2) at x0 =
0
And that is what we are getting:-

Hi Shreyas,
I'm copy-pasting Aaron's reply from the other week:
Take a look at
https://github.com/sympy/sympy/issues?labels=Easy+to+Fix&milestone=&page=1&state=open
and https://github.com/sympy/sympy/wiki/development-workflow and let
us know if you have any questions.

I came across this:
>>> from sympy import Float
>>> Float(1.25343)
1.253430
>>> '{0:.2f}'.format(Float(1.25343))
Traceback (most recent call last):
File "", line 1, in
ValueError: Unknown format code 'f' for object of type 'str'
Is this known/expected? Shouldn't it work?
This works:
I have updated my fork of sympy at github (brombo/sympy) and something
strange is happening in my imports.
The following is the result of a python terminal session (using my
updated sympy)
>>> from sympy.galgebra.ga import Ga
Traceback (most recent call last):
File "", line 1, in

I have no idea what's actually happening.
The whole issue sounds like letter case differences in a file name or
something similarly "it's doing almost what I'm thinking".
