A = (1 0 2 = [a1,a2,a3]

       1 1 3

       0 1 1 )

Find a condition on the numbers u,v and w such that [ u, v, w ] is in the span of {a1,a2,a3}. Note that [u, v, w] goes vertically, with u at the top and w at the bottom.

Express the condition in the form; au + bv + cw = d.

How do I do this, with a brief explanation for each step.

I have the indefinite integral of ( 4 / (4-x)(4+x) )

How do I solve this? I tried simplifying it and substituting, which gave me;

integral of f(g(x)), where f(x) = x^-1 and g(x) = 16 - x^2, but I'm not sure what to do next.

Anyway, what I'm asking is; how do I solve this integral, and if possible, is there a general method or rule I can use to integrate f(g(x)) when g(x) does not give a constant?

Thanks

Hi,I need help with this problem...

A new binary operation ? defined on all positive x and y satisfies the folowing.

x?x = x+2

x?y = y?x

x?(x+y)/x?y = (x+y)/y

given the above, find 11?8

please show how you figured it out.

Thanks

hey, im just looking for a pointer with Question 2 in my 2009 gauss problems, not an answer.

QUESTION 2

Let ABC be a triangle. Locate the point O inside the triangle ABC such that for points L,M and N on sides AB, BC and AC respectively, the triangles BOL, COM and AON have equal area.

LO is parallel to BC. OM is parallel to AC. NO is parallel to AB

how does it mean 'Locate O', how do i show if i have, how do they want the answer represented???

thanks

Hi,

When i Boot my computer up, after about a minute it will freeze. This happens on the login screen and the desktop and the mouse doesn't lock up. So I restart my computer and it will work normally, but if i restart it again or shut it down again it will freeze again. This happens in a consistent cycle of freezing and working. None of my anti virus programs find anything (McAfee, CounterSpy, Avast, Malawarebytes). I have also checked my registry with scanReg and RegCure to no avail.

I tried formatting my drive but after about a week the problem started again.

I am running Windows XP pro SP3 with Intel x2 2.2ghz and an N-videa 8600GT. I have all latest drivers for all hardware installed (I have checked all compatibilty and for hardware problems in device manager).

Thanks

will reinstalling windows xp on my eeepc remove all of the software that came on it, like the super hybryd engine and the custom keys stuff?

if so how would i get it back?
