## Homework Statement

Suppose v = <-3,-2, 1> and w = <-1,1,1>. Then

projw(v) = < -2/3, 2/3, 2/3 > ,

and the component of v perpendicular to w is?

## Homework Equations

## The Attempt at a Solution

I understood how to get the projection, and tried using the component formular Compaonb= a*b/magnitude( A )

But did not get the correct answer which is w2 = < -7/3, -8/3, 1/3 >

Where did I go wrong?
