Hello all,
I would like to obtain the derivative of f(g(x)) with respect to x, using the chain rule, without declaring dependencies. So I thought I'd try pdiff.
kill(all);
load(pdiff);
ans:diff(f(g(x)),x);
g (x) f (g(x))
(1) (1)
ok, but now I want it back into the 'normal' diff format
convert_to_diff(ans);
d d !
(-- (g(x))) (------- (f(g16016))! )
dx dg16016 !
!g16016 = g(x)
I was hoping on an answer without the '16016' stuff. A bug?
Best regards,
Nijso
