I want to repost part of my question: Questions concerning quotient spaces specifically collapsing a set to a point.

One of the commenter stated that I have included like ten questions in a single post. I want to break up the questions into groups and also, since the question mainly have to with visualising quotient spaces, I would like to ask what I can use for including simple illustrations. Do I go with the route that require me to learn more latex. Also, how do I insert illustration underneath each question instead of being in a separate places within the post.

Thank you in advance.

  • $\begingroup$ You can add images, but it's discouraged by most ( partially because of screenreaders, partially because an asker is unlikely to be able to describe the image well enough, partially because We have MathJaX for basic diagrams). $\endgroup$

  • $\begingroup$ @RoddyMacPhee can it also show how an interval on $\mathbb{R}$ collapses to a point. $\endgroup$

  • $\begingroup$ @RoddyMacPhee if I have an interval ((a,b),[a,b], or [a,b)) and I declare every element in that interval to be equivalent in the sense of being an equivalence class, that interval is not a circle. It just becomes a point or a single element. $\endgroup$

  • $\begingroup$ To see what people use to created pictures (for the purposes of posts on Mathematics and also for other purposes), you can check this post on meta: Creating diagrams. And in the comments you can find links to some other posts concerning this topic. $\endgroup$
