Question

The projection of v=(6,4) onto w=(1,1) is _____

Answer 1

you have formula to do it. what is it?

Answer 2

p=(v(w))/(absolute value of w)

Answer 3

I get (10)/(absolute value of (1,1))

Answer 4

\(proj_a u =\dfrac{u\bullet a}{||a||^2}a\)

Answer 5

your a is w, your u is v. Apply it. show your work, please

Answer 6

Proj of v onto w=v.w/||w|| times w

Answer 7

hey kid, the denominator is power of 2.

Answer 8

yes old man just forget it :)

Answer 9

I am busy now, but you must teach me how to do that grid later, kid?

Answer 10

just a visualization of what is going on

Answer 11

So then wouldnt it be 10?
because after plugging in the numbers I get 10/1 which is just 10

Answer 16

|a| can be thought of as the length of a vector from (0,0) to the point a
use pythagoras. e.g. if a=(x,y) then |a| = \(\sqrt{x^2+y^2}\)

Answer 17

Okay

Answer 18

explain more because that kinda confused me
