Let $y = f\left({x}\right)$ be a real function which is continuous on the closed interval $\left[{a..b}\right]$ and differentiable on the open interval $\left({a..b}\right)$.

Let $y = f\left({x}\right)$ be a real function which is continuous on the closed interval $\left[{a..b}\right]$ and continuously differentiable on the open interval $\left({a..b}\right)$.

Let $x=f\left({t}\right)$ and $y=g\left({t}\right)$ be real functions of a parameter $t$.

Let these equations describe a curve $\mathcal C$ that is continuous for all $t \in \left[a..b\right]$ and continuously differentiable for all $t \in \left(a..b\right)$.

differentiate both sides WRT $x$

Declaration of Intent
If I put a proof on PW, I give it to the readers of PW, to help people learn math. You do not need to ask my permission to change the style, language, and notation of my proofs (though of course I might change your changes). If you'd like, tell me on my talk page why you changed it.
