Question: e parallel to w = calculated the 2 x 2 matrix Q that projects vectors onto the line Calculate the 2 x 2 matrix

e parallel to w = calculated the 2 x 2 matrix Q that projects vectors onto the line Calculate the 2 x 2

e parallel to w = calculated the 2 x 2 matrix Q that projects vectors onto the line Calculate the 2 x 2 matrix 1 |w|2 ww, and check that it is equal to Q. Is the matrix symmctric? Usc Q to calculate the projection of the vector (2) onto l. (Hint: note that w7 w and ww are different.) 1 (b) (Bonus question) Explain why ww" is always equal to the projection matrix |w|2 onto w, starting from the usual formula for the projection of v onto w, Pwv|v| cos 0 where is the angle between v and w. W |w|'
