Question

Given x=(1,1,1,1)^T and y =(8,2,2,0)^T

b) Find the vector projection of p of x onto y

Answer 1

what is 'p of x'

Answer 2

are you just projecting x onto y?

Answer 3

yes, projecting x onto y

Answer 4

\[\frac{x\cdot y}{y\cdot y}y\]

Answer 5

so do the dot product of x and y then the dot product of y and y

divide the two...then multiply by y

Answer 6

ok, it is just there is just so many formula to memorize in linear algebra

Answer 7

thanks so much
