Happy Root Day!

Today is 4/4/16 – a square root day. There are only 9 root days each century. They are:

• 1/1/1
• 2/2/4
• 3/3/9
• 4/4/16
• 5/5/25
• 6/6/36
• 7/7/49
• 8/8/64
• 9/9/81

So, celebrate like it’s 3/3/09.

Latex for WordPress

I’ve just installed ‘Jetpack‘ which comes with $\LaTeX$. This post is to provide a quick reference. $\LaTeX$ parses the text in the WordPress post, and lays out the display as a graphic for the viewer. Though someone reading this will see images, there are no images referred to in the edited post.

$\LaTeX$ is a generalised document layout language, but as far as I am concerned, the main use of $\LaTeX$ in WordPress is mathematical.

Note that as the images are generated on the fly, the page will be slower to load than if the page were pre-rendered. Therefore, I think it may still be best for the web to generate the image, save it and then display the result via an <img> tag (keeping the $\LaTeX$ hidden in a comment so that the image can be regenerated if need be). As already mentioned, I have not pre-generated the images for this post, it is all done in code.

It’s a pity that MathML isn’t well supported at the moment.

Integration

The integral of t-squared dt,
From one to the cube root of three,
times the cosine,
of three pi over nine,
is the log of the cube root of e.

Okay, it’s not original, but I like it.

Happy Pi Day!

Today is Pi Day, in the american style the date is 3.14

Of course, elsewhere we use dd/mm/yyyy, so Pi Day would be 31st April, but then the divider is in the wrong place, so lets go with the yanks on this one.
