What is 15 Spiritual Cubits in measurement? —Preceding unsigned comment added by 68.23.169.220 ( talk) 06:46, 28 January 2008 (UTC)
Is there a name for this specific series of numbers: 2, 4, 8, 16, 32, 64, 128, 256, etc.? It's not multiples of two because six isn't in that list. It's just two to various powers but I was wondering if there's a specific name for the series. Dismas| (talk) 09:17, 28 January 2008 (UTC)
I've been self-teaching calculus, so I'm not sure if I have covered the material required for these problems with sufficient depth yet:
f is a polynomial, integrate by parts: 0ƒπ f(x)sinx dx
(that's a definite integral from 0 to pi; I can't figure out how to display it right)
I'm stuck at f(pi)*cos(pi)- ƒ(cos*f'); it keeps looping around from f(x)sinx to f'(x)cosx and so on and so forth.
Is there anything else I need to do, or am I just missing something? Any help would be appreciated.
And I have no idea what's going on here:
g is defined for 0 ≤ x ≤ r by g(x) = qx(r-x), verify:
g(0) = g(r) = 0
g(x) > 0 for 0 < x < r
max g(x) = g(r/w) = qr2/4 = p2/4q
Is r special, or is it just a second variable? What about q? Where did p come from? Pointers to what I need to teach myself, useful pages, or perhaps a walkthrough of a similar type of problem would be most helpful.
Many thanks,
