How to write two dot above a letter?

the two dots above a letter represents two derivative of varible t.
My method:
documentclass[UTF8]{ctexart}
usepackage{amsmath}
usepackage{amssymb}
usepackage{graphicx}
usepackage{epstopdf}
usepackage{inputenc}
begin{equation}
"{o}
mathaccent{o}
end{equation}
However,the latex says in the math environment ,I must use the mathaccent. So I replace " by mathaccent, but it shows the warning information: Missing number, treated as zero
I am a starter, I want to know how to revise it? Can someone help me? Thanks sincerely!!

Welcome to TeX.SE. Use$dot x$for the first derivative,ddot xfor the second,dddot xfor the third,ddddot xfor the fourth.

The sequence
"{o}
will be used when you want to write 'ö' in text, such as 'Schrödinger'.
While in the math mode, as Peter Grill mentioned
dot{o}
ddot{o}
and so on, should do the trick.
Edit:
For more than two dots, e.g. dddot{o}, you need the package amsmath, which allows you a maximum of 4 dots ddddot{o}
(not strikingly beautiful
)
For higher dot derivatives take a look at this post
