I asked a question a few weeks ago about 'splitting' the derivative. The thread can be found https://www.physicsforums.com/showthread.php?p=3581188#post3581188"
The answer to why it can not be split is because dx does not exist, it is simple a notation and not a fraction.
However, I just started Differentials and Errors, and the paper I read said.
The ratio of the two derivatives is actually the derivative of the function.
[itex]f'(x)=\frac{dy}{dx}[/itex]
and the relationship between the two differentials can be given by
[itex]dy=f'(x)dx[/itex]
Is this not 'splitting' the derivative?
Thank you
