Hello,
I'm afraid trigonometric simplification is a known weakness of sympy. On
the other hand, there is good news in your case: *very* recently
(yesterday?) we pushed a new function called ratsimpmodprime. It can be
used as follows:
In [2]: ratsimpmodprime((-sin(x) + 1)/cos(x) + cos(x)/(-sin(x) + 1),
[cos(x)**2 + sin(x)**2 - 1],
gens=[cos(x), sin(x)])
Out[2]:
2
──────
cos(x)
(You can even omit the gens=... argument).
How is that? :-)
We should probably try to incorporate this into trigsimp. That is a
fairly non-trivial project, however ...
Best,
Tom

if you apply trigsimp on "(-sin(x) + 1)/cos(x) + cos(x)/(-sin(x) + 1)"
function
sympy result : (-sin(x) + 1)/cos(x) + cos(x)/(-sin(x) + 1) (dosent
solve anything)
maxima result : 2/cos(x)
what am i missing in sympy ?
Is there any way i can use maxima under sympy ? Or is there any other
way by which i can solve this epxression ?
Thanks,
