# Test of MathJaX

Here is the displayed-math

\int_0^{2\pi} \sin x\rd x,

and the inline math $x>0$. Of course you can put math between the nonmath label to escape the process of MathJaX, for example $x>0$, is produced by the following code:

$x>0$


Now, I will turn to test some new environment, like theorems:

## Theorem 1

• A genotype matrix G.
• The Rows of the matrix are individuals/ taxa.
• The columns of the matrix are SNP sites/ characters.

which is produced by


Theorem 1

A genotype matrix G.
The Rows of the matrix are individuals/ taxa.
The columns of the matrix are SNP sites/ characters.



similarly, I also defined an environment of example, as:

## Example

This is Example 1, can you see the title, if you cannot see, what is the problem did you think there it is?

• A genotype matrix G.
• The Rows of the matrix are individuals/ taxa.
• The columns of the matrix are SNP sites/ characters.

The aboving example can be produced by the following code:


Example
This is Example 1, can you see the title, if you cannot see, what is the problem did you think there it is?

A genotype matrix G.
The Rows of the matrix are individuals/ taxa.
The columns of the matrix are SNP sites/ characters.



The next thing I want to do is make these objects/ environments auto-numbering and cross-ref possible. If you are also interesting in it, maybe you can help me out here.
