I believe that it should be: \begin{align*}\frac{\partial}{\partial{t}}f(x+c(t-\tau ),\tau)&=f_x(x+c(t-\tau ),\tau)\cdot...

I think this is correct yes. (Nod) And we can simplify it bit more since $f(y,\tau)$ does not depend on $t$. Therefore $\pd{}t f(y,\tau)=0$....

Brainstorming some more, I believe we are approximating $y(x)$ with its Fourier form, which is: $$y(x) \approx \sum_{j=1}^{n-1} a_j \sin(jx)$$ It...

If $\phi(x)\ne 0$ then we must have that $x\le \beta$ yes? And $\beta \le |\beta| \le \max(|\alpha|,|\beta|)$ isn't it? So if $\phi(x)\ne 0$ then...

1. Hi Peter,

Thank you for pointing this out to me. I will talk it over with the staff.

In the future there is a "report" button for posts which will create a thread in the staff forum for us to review. This is just for your convenience and to keep things less public if you like. I don't mind you reaching out to me in any way that you like.

Best,
Jameson
2. Hello Peter,

When I first saw that post, I saw that Adrian (Ackbach) had replied to it, so I didn't think much about it. The user to whom Wilmer was addressing his post was already on staff radar as being a potential spammer. Wilmer's posting demeanor can be a bit rough sometimes, but he means no harm as far as I can tell.
3. Sometimes editing a thread title is an issue, but the issue is with vBulletin. If you ever want to change a thread title, and can't, just let me know and I can fix it.
4. Hey Peter!

I edited your post to remove the duplicate content. Sorry for the late reply, I was busy "powering through" a tedious 3 hour project.
5. Glad to hear that resolved the issue! I thought perhaps forcing your browser to reload the script by removing it from your cache might do the trick.
6. Hmmm...have you tried clearing your cache on your iPad?
7. Hey Peter,

No, there have been no changes in that regard, at least that I know of. Do you visit any other sites that use MathJax? If so does it render there?

Best Regards,

Mark.
8. Good deal, Peter! I wish I had a nickel for every time a problem is corrected by ditching IE and using a modern standards compliant browser.
9. I would try another browser...IE is notorious for being problematic.
10. Hello Peter,

No changes to composing posts have been made. What browser are you using? What OS?
