Does "dx" does not make change in front of the integral?
Hello I got one question. I am confused by seeing dx in front of the integral.
For ex.
[tex]\int f(x) dx = F(x) + C[/tex]
where
[tex]F'\!(x) =\frac {d}{dx} F(x) = f(x).[/tex]
As we know F'(x)=f(x), then why F'(x) = f(x) . dx
Isn't supposed to be F'(x)=f(x) and not F'(x)=f(x) . dx??
Thanks in advance.
