ok stupid question probably-(adsbygoogle = window.adsbygoogle || []).push({});

take v(velocity) to be a function of x and x to be a function of t(time).

then dv/dt=vdv/dx thats cool

but in the hint in problem 2.12 classical mechanics by john r taylor he equates vdv/dx and 1/2(dv^2)/dx

that is- vdv/dx=1/2(dv^2)/dx

Could someone please explain this?
