Question

A small doubt about differentation

Answer 1

Why cant we do this:
\[f^{'} (2x)=\frac{d}{dx} f(2x)\]

Answer 2

@Mashy

Answer 3

I think we can do this. It will be just like f'(x), but you have to apply the Chain Rule, because 2x is another function.
I hope this rings a bell...

Answer 4

no..its written its wong

Answer 5

the correct way is,perhaps
\[\frac{d}{d(2x)} f(2x)\]

Answer 6

do you want the derivative of 2x?

Answer 7

yes

Answer 8

that would be f'(X) = d/dx 2x
(sorry for the late reply)

Answer 9

\[f \prime(x) = \frac{ d }{ dx } 2x\]
