Probably isnt the bst site for ....but if anyone has taking first year linear algebra, and is good at it, maybe i could PM them a few questions, thanks
“The 22 Rules That Turned Me From Invisible to Irresistible With Women… Starting Tonight”
You can skip the expensive cars, the fancy clothes, and the endless gym selfies. Completely unnecessary.
I used to freeze the second a beautiful woman looked my way. Frustrated. Awkward. Watching other guys walk away with the girl while I stood there tongue-tied.
Then I discovered 22 simple rules that rewired my entire dating life. The anxiety vanished. Conversations flowed effortlessly. Women started chasing me for a change.
These rules trigger a woman's subconscious attraction switches. And you can start using them tonight.

Just because a woman listens to you and acts interested in what you say doesn't mean she really is. She might just be acting polite, while silently wishing that the date would hurry up and end, or that you would go away... and never come back.

What's your question?

fine fine
Question 1: Show that every set of vectors from P2 are linearly dependant
Question 2:Let T:R3-R3 be a linear transformation defined by:
T(x1,x2,x3) = (x3, x1+x2+x3, -x3)
*Prove T is a one-to-one operator
*Find T-1 (w1,w2,w3)
Question 3: Determine whether A is a subspace of ( all m2x2 matrices)
A=[a b]
[o c] (one matrix) [a,b,ER]

What exactly is giving you trouble in these problems? I'll help you figure out concepts, but I'm not going to do anything that a professor won't approve of.

Turn this into a matrix and take the determinant. You know what they say when the determinant of a matrix is NOT zero?
As for the rest, sounds like it's in some obscure notation that no engineer would ever use. Unless all the students in that class are going to be publishing the American Journal of New Discoveries in Annoying Subscripts, I don't think you need to know it.

Notations were the most annoying things I had to deal with in math classes.
What are you guys' majors btw?
Never mind, i'll make a new thread asking that.
