Test post with Math in it

This is an equation: 2 \sin \theta. How does it look? I used the WP-KaTeX plugin for WordPress. WordPress is the web software that runs this blog. I tried the Simple MathJax plugin but it displayed at about half the point size of the surrounding text. WP-KaTeX also has the same problem but not nearly as bad. My company, Design Science, helped found MathJax and supported it for a couple of years. Makes me sad that I didn’t get a better out-of-box experience. Oh well.
