How To Use It

What's this?

This is a web service which provides a function to generate an image of a mathematical expression so that you can embed it to your Blogs, Wikis and so on.

Let's make an image for a formula

There is the form for making an image for a formula in the top page. You can share the formula of which you're interested from the form by entering a mathematical expression.

Preview of the expression is rendered once 3 seconds so that you can see the figure of the formula. If you get a pleasing result, let's share the formula by clicking the submit button. And then, the page has a HTML snippet to embed the image to your blogs.

Embed a formula into your blog post

You can embed a mathematical expression by writing a blog entry including a HTML like this

<a href="http://formula.s21g.com/?f(x)=\int_0^{x}g(t)\,dt">
  <img src="http://formula.s21g.com/?f(x)=\int_0^{x}g(t)\,dt.png" />
</a>

The HTML above will be converted into the image below.

You should wrap the IMG tag with the A tag as presented above. Please note the URIs being slightly different. The URI of IMG tag contains ".png" at the end.

Discuss about a formula

This service provides a place for discussing about a formula.

Each formulae has its page in this site. You can access to the page if you click the link of the A tag explained above. For example, here is the page for the formula appeared in above.

The page has a comment-form so that you can discuss about the formula with others who are interested in it. You need neither registrations nor signing up. Let's get started!

NOTE: To edit a page of a formula, you must leave a comment to the page in order to prevent SPAM. The comment must have your name and password. You can edit the page as long as the comments you left exist.
