How do I add graphics to my post?


#1

There are a couple of ways to add mathematical graphics to your post.

  • Via the upload button or
  • Via a Geogebra interactive graph

Note that this question only concerns how to add these things once they’ve been created. The actual creation of images in the first place is outside the scope of this question but you can ask about that kind of thing in the code category.

Image upload

When you’re in the editor, you should notice a toolbar at the top:

Just click on the Upload button as shown. The process should be self-explanatory. You can upload an image from your computer or link to an image on the web.

Dynamic graphs with Geogebra

Geogebra is a great open source tool that allows you to create interactive graphics online. These graphs can be embedded into an iframe on this site, which is how the image below was produced:

The image shows the graph of y=sin(ax) and is interactive. You can move the slider to change the value of a and see the effect.

Desmos

You can also use Desmos; it’s even easier than Geogebra:

To generate that, I just pasted the following embed code that I got out of the share link on Desmos:
