cannot number equation based on section or chapter

[GoogleCodeExporter]

(Please attach an example .tex file demonstrating the problem or bug.)

Please describe the feature, problem, or bug:
I wanna number the equation within section. Using the command:

\usepackage{amsmath}
\numberwithin{equation}{section}

In default "book" class, it works fine, shows such as 1.1, 1.2, 2.1, 2.2.
But in "tufte-book", it cannot work

What is the expected output? What do you see instead?
The expected output 1.1.1, 1.2.1, 2.1.1, 2.2.1
But tufte-book output 0.0.1, 0.0.2, 0.0.3, 0.0.4

What version of Tufte-LaTeX are you using?  With which TeX distribution?
tufte-latex-3.5.0
TeXlive 2012

Please provide any additional information below.

Try increasing the secnumdepth counter.  Add the following to the preamble of 
your document:

    \setcounter{secnumdepth}{1}

Note that this will cause the chapters and sections to be numbered as well.

Can you help me it keep enumerate like this:

0.0.1, 0.0.2, 0.0.3, 0.0.4
