Am I wrong or not -- I thought Newton only developed the overdot notation for the derivative? Dysprosia 08:16, 11 Oct 2003 (UTC)

This page may not be authoritative.

I'm right! Yay :) (I'm not right often ;) I thought the guy that created the prime notation had a name starting with L - Lagrange, here's a ref [1], I'll change these accordingly Dysprosia 08:21, 11 Oct 2003 (UTC)

I changed the interpretation from

\dot{x} = \frac{dx}{dt} = f'(t)
\ddot{x} = f''(x)

to

\dot{x} = \frac{dx}{dt} = x'(t)
\ddot{x} = x''(t)

Due to pages from the BBC and from the University of Texas at Austin

As written it was saying that the derivative of x with respect to t was somehow also the derivative of f with respect to t in one place and the derivative of f with respect to x in another place.

[edit] Use

Does anyone know if this notation is actually used today? I've asked several a few math professors and some didn't even know it existed, while the others said it was never used.
