# How to ensure enough spacing between the equation sign and LHS expression

I am trying to type the following math equation:

\documentclass{article}

\begin{document}

$\mid \alpha'(t) \mid = \left< \alpha'(t), \alpha'(t) \right >_p$

\end{document}


My question is regarding the equation sign; there is decent spacing between the '=' and the expression on the right, but it ends up being too close to the expression on the left. Is there a way to ensure enough spacing between '=' and the LHS?

Thanks

• I think you mean that = is too close to the left hand side, not the right hand side? – David Carlisle May 2 '18 at 20:52
• You're right, I apologise for the confusion. I have edited my question – T J. Kim May 2 '18 at 20:53

The problem is your use of \mid which is an infix relation.

\documentclass{article}
\usepackage{amsmath}
\begin{document}

$\lvert\alpha'(t) \rvert = \left< \alpha'(t), \alpha'(t) \right >_p$

\end{document}

• @TJ.Kim something like + in a use such as a \mid b to make "a | b" – David Carlisle May 2 '18 at 20:55
• @TJ.Kim Prefix: + a b. Postfix: a b +. Infix: a + b. – Au101 May 2 '18 at 20:58
• @Au101 thanks for pointing out the distinction – T J. Kim May 2 '18 at 21:00
