Thank you for your reply.
I suceeded to run the code.
>>> f = Function('f')
>>> x = Symbol('x')
>>> diff(f(x),x)
D(f(x), x)
How about second derivatives ?
I mean
diff(D(f(x), x),x)
Is there any way to get the answer ?Thanks in advance, czbebe On 2009年12月28日, 午後11:11, smichr <[email protected]> wrote: > On Dec 28, 12:04 pm, "[email protected]" <[email protected]> > wrote: > > > Dear members, > > > When function f is a function of x, sympy diff output is diff(f,x) = > > 0. > > I hope output should be dx(f).
