Linear algebra question

Answer 1

I can't figure out the right answer >.> .

Answer 2

this is homework

Answer 3

I know.

Answer 4

your a cheater

Answer 5

The heck? What wrong with asking for help? Troll.

Answer 10

It's not a test or anything. Really!

Answer 11

but you said to me you know it's your homework

Answer 12

What's wrong with asking if I don't get how to solve a question?

Answer 13

I tried using the formula but it doesn't work after taking the norm.

Answer 14

but don't post your homework up there to get answers

Answer 15

But I just need an explanation >.> .

Answer 16

Why is my procedure wrong?

Answer 17

post like a example are something but not your homework

Answer 18

You aren't helping the situation.

what I'm saying don't post your homework post a example not your homework

Answer 20

I could have lied and said this was an example.

Answer 21

well i'm sorry for all this

Answer 22

You are asking questions too. Hypocrite.

Answer 23

Ok, everyone, lets help Dido. He/She says it is not a test - and that he/she is allowed to get help. Lets help. And Dido would you mind accepting 50-c apology graciously?

Answer 24

yes Preetha

Answer 25

Yeah sure. He didn't need to get like that though.

Answer 26

what you need help on @Dido525

Answer 27

I don't see what I am doing wrong. I use the formula provided and I take the square root. I am not getting the right answer.

Answer 28

so basically the question asks for inner product and you are given the vectors p and q

Answer 29

Yeah.

Answer 30

Well, the distance rather.

Answer 31

And distance is just norm.

Answer 32

d represents distance from ?

Answer 33

I ASSUME P to q. I am not sure about that though.

Answer 34

what is d(p,q) what is the d?

Answer 35

d meaning distance.

Answer 36

so magnitude of this vector?

Answer 37

distance between 2 polynomials.

Answer 38

Doesn't work if I do that.

Answer 39

(p,q) = innet product so d(p,q) = distance of inner product waat?

Answer 40

d(p,q) is the distance between the two polynomials p and q.

Answer 41

You could say the norm as well.

Answer 42

oh ok whats the point of that inner product formula then

Answer 43

That's the thing. I am confused about that.

Answer 44

If I just used the norm formula I don't get the right answer.

Answer 45

i vaguely remember having to take integrals of innerproduct but i forgot why i did that

Answer 46

Erm... I don't think that's necessary...

Answer 47

ohh for fourier series stuff

Answer 48

Lol!!! That's beyond the scope of our text.

Answer 49

i was just wondering that inner product word sounded familiar its stuff u do for fourier series

Answer 50

How is \(d\) defined here?

Answer 51

I assume d is distance.

Answer 52

what formula for distance is being used?

Answer 53

did u try just multiplying em together and entering it

Answer 54

I am guessing the formula for norm but I am not getting the right answer if I use that.

Answer 55

what answer did you get ?

Answer 56

Remember that \[
\|a\|^2 = <a,a>
\]

Answer 57

Well the correct answer is 3 but I am not really sure how it is that.

Answer 58

yeah, i get 3 also.

Answer 59

The heck? How??

Answer 60

d(p,q) = ||(q-p)|| =.... ?

Answer 61

first find q-p

Answer 62

Umm okay.

Answer 63

OOO!!! I see it!!

Answer 64

Thank you!!

Answer 65

:)

Answer 66

welcome ^_^

Answer 67

Man, I thought my hint would be helpful!
