Hi,
I'd like to intergate a function f with NIntegrate:
NIntegrate[f[x], {x, 0, 0.1}]
But this doesn't work if, i.e.
f = NIntegrate[Sin[x + #], {x, 0, 1}] &
It will give a wrong result (0.7 instead of 0.05). Why? I mean, I can
evaluate f at any point without problems, i.e. f[0.1] gives 0.37. So why
doesn't
NIntegrate[f[x], {x, 0, 0.1}]
work? It doesn't even give a warning! So, is there a proper way to do this
(without using one two-dimensional NIntegrate)?
Regards
