Find the projection of u = <–6, –7> onto v = <1, 1>.

If you are going to post your questions 10 times an hour no one will answer it.

Formula

proj _v u    =  dot product (u, v)

                  _______________   *      b        =

                 (  magnitude of v)^2

-6*1   +  -7*1

___________ *   ( 1 , 1)     =

  1^2 + 1^2

-13

___  * (1 , 1)     =

  2

(13/2, 13/2)
