This is a simple dummy question. What are the conditions under which the following relationship holds,(adsbygoogle = window.adsbygoogle || []).push({});

dx/dt = Inverse(dt/dx) = 1/(dt/dx)

meaning if I want to do a derivative and I know t(x) but not x(t) when can I just calculate dt/dx and put it over 1 to get dx/dt. I see this in derivations a lot, but always wonder what the realm of applicability is.

thanks.
