Default Ping Ig, anyone with kids in school--Mathforum.org

Really neat--

Can submit Q's, and volunteers will email you a response, god willing.

The link below was an inneresting ditty on calculating arc length of a sine
curve. Archived from 1996!!

http://mathforum.org/library/drmath/view/52038.html

The answer was 7.64.

I submitted a Q, asking if the ratio of the circumference of the circle
generating the sine curve to the arc length of the sine curve was constant,
ie, independent of the radius of the circle. ie, 6.28/7.64.

If so, arc length of sine curves et al are readily inferred.

Yeah, ahm bored at home....

Very nice. Do they still have any people who participate?

Tutors on algebra.com answered this many questions on recent days:

158 2007-09-16
150 2007-09-17
142 2007-09-18
159 2007-09-19
145 2007-09-20
150 2007-09-21
103 2007-09-22
196 2007-09-23
148 2007-09-24
97 2007-09-25

(2007-09-25 is today, a partial day)

Here are the stats of percentage of problems solved as percentage of
problems asked:

ak74::~==percentage-solved
Last 1 days: 228 solved, 155 unsolved, 59% solved.
Last 3 days: 491 solved, 265 unsolved, 64% solved.
Last 7 days: 1042 solved, 549 unsolved, 65% solved.
Last 10 days: 1469 solved, 694 unsolved, 67% solved.
Last 30 days: 3960 solved, 2091 unsolved, 65% solved.
Last 90 days: 9650 solved, 4208 unsolved, 69% solved.

So, about 2/3 of problems are answred.
