Question

easy lgbariddle:

Answer 1

when is:
\[\Large \frac {\text d} {\text d x} [\int f(x) dx] \ne \int [\frac {\text d}{\text d x} f(x) ]\]

Answer 2

im thinking something with logs? im tired..

Answer 3

Shouldn't they always be equal? (Not counting the extraneous constant, if you count that, then they're never equal)

Answer 4

it's easier than you think lol

Answer 5

when f(x) is constant

Answer 6

\[
f(x)=c, c\in\mathbb{C}
\]

Answer 7

right when f(x) is constant is right.... lgba hence solved

Answer 8

\[\huge{\color{blue}{f(x) = c , \textbf{c denotes constant }}}\]

Answer 9

hah nice. that just proves he who knows not much thinks the simplest

Answer 10

:P well nice way of proof ... haha I thought of some heard at first but I just noticed easy riddle..
thought of some easier and got this

Answer 11

Actually as u know

integration of 0 will give integration constant (C)
while
differentiation of (cx + C) will give c

so, c not equal to C you get ur case

Answer 12

Bah! Humbug!
