hmph. it seems you've edited it on me

Can you write the last part of that out to make it a little clearer? I can't understand exactly what you mean.

Oh. We defined it as whatever part of R^n that V isn't in

I do not know. Help prease!

Wouldn't V^\bot just be the left nullspace of B?

If V = C(B), the column space of some matrix B, then Bv = 0

That a vector v is contained in V perp That a vector Av is contained in V perp

I still am not sure what to do. Any further helpings?

Homework Statement Suppose that A is a real symmetric n × n matrix. Show that if V is a subspace of R^n and that A(V) is contained in V , then A(V perp) is contained in V perp. Homework Equations A = A_T (A is equal to its transpose) The Attempt at a Solution I have no idea...

(this is not homework) Suppose I wanted to solve: \int log(x) log(x+1) dx from 0 to 1. I would turn ln(x+1) into a series, namely, –∑(-1)^n * x^n / n Any ideas? Besides substituting, pulling out the n's, and using intgration by parts?

It isn't homework... as I'm not in a class. But it is a "problem," so I actually reposted it in the HW section.

Homework Statement Find the average area of an inscribed triangle in the unit circle. Assume that each vertex of the triangle is equally likely to be at any point of the unit circle and that the location of one vertex does not affect the likelihood the location of another in any way. (Note...
