Question	—	Posts with math are very, very tall in the feed With the recent post previews, posts with previewed math end up becoming ridiculously tall Screenshot tall posts in post list This obviously both looks ugly and means that fewer posts can fit on the page at once. There are two main ways that I think this could be resolved: forcing inline... (more)	—	over 1 year ago
Answer	—	A: Show that $\forall n \in \mathbb{Z}^{+}$, $25^n \equiv 25 \bmod{100}$. There is a fairly simple proof by induction. Base case: $n = 1$ $$25^1\equiv 25 \mod 100$$ Inductive case: Assuming $25^n\equiv 25 \mod 100$, $$ \begin{align} 25^{n+1}&\equiv 25\cdot 25^n \mod 100\\ &\equiv 25 \cdot 25 \\ &\equiv 625 \\ &\equiv 25 \end{align} $$ Actually, th...

Answer	—	A: In the Monty Hall problem, why can you just assume the contestant picked door 1? Why are you entitled to relabel the doors, or rewrite this solution with the door numbers permuted? > Correct me if I'm wrong, but the game show didn't authorize contestants "to relabel the doors, or" permute the door numbers. So what permits you to do any of this in this solution? The game show never labeled the doors in the first place. We are the ones labeling the doors, so we are free to lab...

Answer	—	A: Who should the temporary moderators be? I'd like to nominate Peter Taylor I think that Peter would also be a good mod candidate. He is also quite active here, and also seems to be active on Math Meta. If Peter would like to accept this nomination, please let me know. (more)	—	almost 3 years ago
Answer	—	A: Who should the temporary moderators be? I'd like to nominate Derek Elkins I think that Derek would be a good mod candidate, as he is relatively active here both as an answerer and on Math Meta. If Derek would like to accept this nomination, please let me know. (more)	—	almost 3 years ago
Question	—	MathJax doesn't render in thread previews Basically the title. For example, see this post; the LaTeX code isn't rendered when opening the preview. (more)	—	almost 3 years ago
Question	—	Equations can be too big for the post area On https://math.codidact.com/posts/280741, there is a pretty big table on the question which overflows off the edge of the post and into the side widgets. Screenshot of overflow Clearly, this shouldn't happen. Perhaps once it reaches the border of the post, it could be resized to fit in the pos... (more)	—	about 3 years ago
Answer	—	A: Mathjax does not render new lines Tl;dr, Markdown and LaTeX don't like each other The problem lies in a conflict between the Markdown and MathJax parsers. The Markdown parser runs first[^1] and uses \\ as an escape character, and so `\\` becomes a single backslash. The MathJax parser then only sees that single backslash, which mea...

Answer	—	A: Why does the decimal expansion of $1/(10n - 1)$ have this neat pattern? I was pretty curious about this, so I posted a question on Math.SE. Most of this answer will draw from the idea of J. W. Tanner's answer there. There is actually a simple reason why this pattern holds. Lets start by examining how the digits are generated: each digit is a power of two (with ... (more)	—	over 3 years ago
Question	—	MathJax rendering freezes post editor I've found that while typing a post, whenever the MathJax renderer runs the editor freezes and I become unable to type anything in it. This is quite annoying, as it happens quite often - I can only type a few words before the MathJax renderer runs and stops me. Even just moving the caret with arrow k... (more)	—	over 3 years ago
Question	—	Expanding comments de-renders MathJax See the comments on https://math.codidact.com/questions/278629#answer-278638. When I click "Show 1 more comments", all the comments revert to raw LaTeX. Without expanding: Unexpanded comments After expanding: (more)	—	over 3 years ago
