Hey Everyone,
I have this question on my assignment that's confusing me, I think I have the logic right, but for some reason Im getting the wrong answer..
Anyways the question states:
If S is the subspace of M5 (R) consisting of all matrices with trace 0, then dim(S) = ?
Now, I know...
Hmmmm, yes you are right, if it is in the plane it's impossible.
Im really sorry for all your trouble, I really appreciate your help!
But assuming V is not in the plane, would it be possible? :smile:
That's not really what's being asked in the question, we dont want the projection of A onto V, we just want an a general expression for projecting A on the plane by just adding a multipe of V to it.
Any ideas? :frown:
Hey Everyone,
I have this question that's been giving me a hard time, I dont really know how to do it.
"Let A be an arbitrary vector. It may be projected along a direction V on the plane P with normal vector n. What is its image A` ?"
I know that A + lamda*V = A` , and that we have to...
btw, the answer I got when I did this was 2.313x10^8 m
there's a hint on that question but it made sense to me.. Here it is just in case: "What is special about the case R2 > n*R1? "
Hey Everyone..
I'm having trouble with this question, I think I have this question figured out but my answer is coming out incorrect... Tell me if there is a flaw in my logic.. question is:
"Suppose that a luminous star of radius R1=1.74×108 m is surrounded by a uniform atmosphere...
Hey Everyone,
I have this physics problem, and I'm not really sure how to solve it using linear and angular momentum, I know it can be solved otherwise in different methods, but I'm interested in this one..
The question is:
"A bowling ball is given an initial speed of 5 m/s on an alley...
Hey Everyone,
This is a quick question.. is binding energy positive or negative? I'm pretty confused now, because in some places the definition was:
The energy released when the nucleus of an atom is formed by combining neutrons and protons.
And in other places:
the energy required to...
Hey guys,
This is just a quick question.. I have a question on my linear algebra assignment that I dont understand..
What does it mean when you're given a 2x2 matrix M and told to "find formulas for the entries of M to the power of n, where n is a positive integer"
The assignment is about...
hey guys I think I might have said the question in a wrong way or something.. the phenomenon i'm talking about is not 3D.. :frown:
It's just a 2D picture, only difference than any normal picture is that it ONLY appears under polarized light.. Helpful? :confused:
No, not really..
It's like a picture, if you look at it with the naked eye, you see nothing, but if you shine polarized light on it you see the picture.. What's the explanation of this?
