f(x).diff(x)

Ondrej,
I think the patches I've attache fix this problem. This is the behavior
I get:
x = Symbol('x')
f = Function('f')

Thanks for the bug report. Seems like a pyglet issue, I reported here:

I don't know the reason of this behaviour, fortunately
changing it did not break any tests.
If all tests pass, it's

Issue 626 is fixed by these two patches. Also, solve can now Symbol,
Function, and Derivative types.
I implemented tests and everything passes on my machine.
Thanks,

Although sympy doesn't yet know how to handle these :(
please note the dual-integrate result
how can I get an advanced value in sympy? thanx
[smypy]
from sympy import *
X,Y=symbols('XY', real=True)
integrate(2*X*X+2*Y*Y-1, (Y, -(1-X**2)**Rational(1,2),
(1-X**2)**Rational(1,2)) )
-2*(1 - X**2)**(1/2)*(1 - 2*X**2) + 4*(1 - X**2)**(3/2)/3

Does anybody use solve() by passing the function and/or the symbol
arguments as a set, rather than a list or a tuple?
I can't see a reason why using it with a set would be beneficial, and
without support for sets, there are some aspects

Just out of curiosity, is there a reason that one has to use the .args

I would like to add code that would allow for diff() to differentiate
with respect to not just Symbol instances, but also with respect to
Function and Derivative instances. An example of why this would be
useful would be when forming Lagrange's equations, on needs to
differentiate the Lagrangian
I get a slightly different result when integrating in Matlab (2008a):
[matlab]
syms X Y L H K;
int(int(2*X*X+2*Y*Y-1, Y, -sqrt(1-X*X), sqrt(1-X*X)), X, L, 1)
ans =
-2/3*(1-L^2)^(1/2)*L*(L-1)*(1+L)
expand(ans)
ans =
2/3*(1-L^2)^(1/2)*L-2/3*(1-L^2)^(1/2)*L^3
[/matlab]
In sympy, it seems
14 matches
