Using TikZ on math.stackexchange

The title pretty much says it all:

How can I use TikZ when writing my math questions on this site?

I have written out my question in LaTeX using the TikZ and it took me quite some time, now I realize I can't just use it here. I saw an older post on this very same question but it was two years old and the answer was that it wasn't possible yet. So I am hoping it might be possible now.

Thanks!

Unfortunately, you cannot use TikZ. Though I would strongly recommend the stackexchange/MathJax personnel (whoever is responsible for it) to incorporate it.

The best way out is to use TikZ on your own machine and copy the image generated and paste it here. This is what I have been doing in the last three years. Below are some of my posts, where I have used TikZ and copy pasted the image from TikZ.

Why is the definition of "limit" difficult to understand at first?

Prove by mathematical induction that $1 + 1/4 +\ldots + 1/4^n \to 4/3$

How to show that $S^1\sim\Bbb R$?

Computing a sum of binomial coefficients: $\sum_{i=0}^m \binom{N-i}{m-i}$

Cosine function is decreasing on $(0,\pi)$

For those unfamiliar with TikZ, TikZ/PGF is a powerful TeX package for creating beautiful vector graphics. You can read more about it and look at some nice pictures here.

• The MathJax "personnel" is the factor to reckon with here, not the SE staff. I recall them stating that since TikZ admits no natural MathML handling, it is unlikely that it will be supported on a shorter time scale. Or perhaps you were suggesting to move away from MathJax; but as the general performance of MJ is nothing short of stellar, this seems unlikely and unnecessary to me, too. I regret it, though. TikZ is great. Commented May 13, 2013 at 20:29
• Thanks for your answer, this is what I was afraid of but copying and pasting does not seem too bad. It needs to be in .png format right? And how do I paste this in a question? sorry I have never used images in my questions. Thanks! Commented May 13, 2013 at 20:32
