# How to type higher order derivatives using Lagrange's primes notation

This is what i have been using but it dosen't look quite right

$$\large y', y^{\prime\prime}, y^{\prime\prime\prime}, {y^{\prime\backprime\prime}}, {y^{\backprime\prime}}, {y^{\backprime\prime\prime}}, {y^{\backprime\prime\prime\prime}}, {y^{\backprime\prime\prime\prime\prime}},\dots$$


### MWE by Qrrbrbirlbel

(\large removed, as it is invalid in math-mode, TeX throws a warning, too):

\documentclass{article}
%\usepackage{amsmath} ?
\usepackage{amssymb}
\begin{document}
$$y', y^{\prime\prime}, y^{\prime\prime\prime}, {y^{\prime\backprime\prime}}, {y^{\backprime\prime}}, {y^{\backprime\prime\prime}}, {y^{\backprime\prime\prime\prime}}, {y^{\backprime\prime\prime\prime\prime}},\dots$$
\end{document}

Welcome to TeX.SE. While code snippets are useful in explanations, it is always best to compose a fully compilable MWE that illustrates the problem including the \documentclass and the appropriate packages so that those trying to help don't have to recreate it. –  Peter Grill Nov 6 '12 at 6:43
y',
y^{\prime\prime},
y^{\prime\prime\prime},

why???? would you want to fake Roman numerals out of primes and reverse primes rather than using letters??????? –  David Carlisle Jul 8 '13 at 11:10
