# Testing MathJax

Following the instructions on Irreducible representation, MathJax works on Blogger.

I typed

and here’s the result: $\cos^2\theta-\sin^2\theta=\cos 2\theta$

Antoher equation:

$ax+\frac{b}{y}=1$

This time, the equation is in display mode.

How about the inline verbatim environment? Googling “mathjax verbatim”, we have

$\verb*x^2\sqrt y* \text{ yields } x^2\sqrt y$

according to $\rm \TeX$ Commands available in MathJax by Dr. Carol JVF Burns. Nevertheless, it only works in display mode.1

Finally, let’s get some equations numbered, just like an example on the MathJax CDN.

$$$\int_{0}^{\frac{\pi}{2}} \sin x \ud x = 1$$$
