UGH. I'm sick of linear algebra and so ready for this semester to be over.

My teacher writes homework questions in a way that I CANNOT understand. Can you help me understand this question:

Suppose that u and v are two linearly independent vectors in R^n, n greater than or equal to 3.

Show that the set of all vectors in R^n that are orthogonal to both u & v is a subspace of R^n.

How do I solve this problem? (Hints are appreciated, Thanks)

Show that the determinant of C, |C|, does not depend on x.

the matrix C =

sin(x), cos(x), 0

-cos(x) , sin(x), 0

(sin(x) - cos(x) ), (sin(x) + cos(x) ), 1

C is a 3x3 matrix with each element separated by a comma

My assignment says to turn in the Karnaugh maps for a BCD counter, but how can a BCD counter have karnaugh maps if it doesn't have any inputs?

You just count using the clock signal, not using inputs. Help? Thanks

1 AnswerProgramming & Design1 decade ago### Linear Algebra: Using Scalar Multiplication to prove that a set is within R2?

I'm studying for a linear algebra test, and I'm having a bit of trouble proving that a set is closed under Scalar Multiplication (I've got Vector Addition down fine).

Here's my example:

Show W = {(x, y) in R^2 : xy = | xy | } is closed under Scalar Multiplication.

I have this so far:

Let λ be a scalar.

Let the vector u = (u1, u2) in W, i.e. u1u2 = | u1u2 |

If you can help me figure out what's next, I will greatly appreciate it. Hopefully this will help me figure out subsequent problems. Thanks.
