A thread from 2007 was recently restarted, and then went off the math-specific track. People were having an interesting discussion (and were being very polite about it), and it has been requested that this discussion be moved to an appropriate location so that it might continue. So here's the...

I've e-mailed Ted, the owner of FreeMathHelp, about these forums. In particular, I expressed to him the feeling amongst some of us moderators that the forums seem to have been set adrift. In response, Ted said that other concerns (his day job, his kids, etc) take up enough time and energy that...

Note: Opinion is very often very evenly split regarding whether the final term on the right-hand side should be interpreted as: . . . . .\mbox{1. }\, \dfrac{d}{2e} ...or else as: . . . . .\mbox{2. }\, \left(\dfrac{d}{2}\right)(e) The "right" answer will depend upon the exercise author's...

I can do the (fairly easy) crossword puzzles that are daily sent to my phone. But this "crypt" stuff is a whole different animal. Is there some "crypts for dummies" site that y'all could recommend, so I could at least start understanding the answers? :shock: Thank you! :p

Actually, that link was removed when the target site ("Karl's Calculus", I think?) disappeared. Another resource can be found here. ;)

I think your derivation was something along the lines of the following: . . . . .converting outer-radius function: y = ln(x) => x = ey . . . . .outer radius: R = ey - (-1) = ey + 1 << MISSING LINE GOES HERE >> . . . . .do volume by discs: outer circle's area, less inner circle's area, . . ...

We've all seen it in the past: A student posts something, usually a lengthy exercise, and asks for help. Once the full solution (or nearly so) has been provided, the student erases his/her original post, leaving it blank -- and leaving the rest of us wondering why s/he didn't want anybody...

I only noticed this issue because I'd replied to a question, but then the question was reposted. Despite the original and second postings both being displayed (and now merged into one thread), the "posts" number under the poster's handle was "1", which is clearly wrong. Puzzled, I checked the...

Q. Where did all of this morning's posts go? Why is there nothing posted since some time "yesterday"? A. At some point since this morning, the database which houses the "back end" of the forums was hacked. The site owner, Ted Wilcox, (yes, he does exist!), rolled back the server to the last...

\frac{1}{3}\, -\, x^2\, \mbox{ and }\, \frac{1}{3}\cos(x) \frac{1}{3\, -\, x^3}\, \mbox{ and }\, \frac{1}{3\cos(x)}

Is anybody else experiencing really slow page-loading? Pages can take as long as a minute to load, with the bottom of the browser showing "transferring data from... google-analytics.com..." In case it makes a difference, I'm using Mozilla on a Vista platform (boo! hiss!), surfing through...

I'm glad to see, in the "Current visitors" listing, that the FreeMathHelp site is being crawled for inclusion (or update) in the various search engines. But less-experienced visitors might wonder if it's "safe" to surf a site with "bots". :shock: Would it be possible to "hide" bots, etc, from...

Shortly after the forum-script update, the default font was changed from smallish and gray (alternating with black) to medium-sized and (always) black, as a kindness to us oldsters who can't see worth a darn. :wink: This morning, the font appears to have reverted back to smallish and...

As near as I can determine, the default color for posts in any given thread is either set to a dark-ish gray, or else alternates between black and gray. In the message-entry/edit box, the background is white, so the text isn't so hard to read. This contrast is nicer. But once you've posted, the...

I have been experiencing frequent "no response" or time-out issues when attempting to view pages here today. Is there trouble at the server farm, or is the issue site-specific? Or is it just me? Thank you. Eliz.

Am I the only one not seeing the links at the top of the page? You know: the "lessons" links, and the "Forum Help" pull-down menu with all the formatting links? Thank you. Eliz. P.S. I'm browsing in Mozilla 1.7.7 on WinXP, if it matters.

Some of the new categories allow for "guest" postings and polls. Also, some categories do not contain the "Read this before posting" message. Could this be fixed? Also, should Differential Equations be merged with Calculus (like Geometry and Trig are together in one)? Diff-EQ doesn't seem to...

Would it be possible to add something along the lines of the following to the "Read Before Posting" sticky-notes? Post to an appropriate category. Questions about derivatives (calculus) do not belong in "Beginning Algebra". Questions about finding the area of a circle (geometry) do not belong...

At first, the forum went wonky and outdated, and then it disappeared entirely, and then the whole site disappeared. Is everything okay now? I hope the problem was just an awful accident, and nothing intentional (like getting hacked or something). And I'm very glad to see that the site is "up...

I recently received an e-mail from somebody asking a question about a pseudo-sequence (that being a list of numbers that might look like a mathematical sequence but whose relationship is non-mathematical). I quickly found that the puzzle that he'd been working on "for a long time" "for fun" was...
