Question

Find the projection of v on to w if v = ⟨-5,-2⟩ and w = ⟨1,-1⟩

Answer 1

Answer:

Step-by-step explanation:

$\frac{\vec v \bullet \vec w}{||\vec w||}\bullet \vec w$

$\vec v \bullet \vec w = \bullet = -5+2 = -3$

$||\vec w ||=\sqrt{2}$

Hence, the result will be

$\frac{-3\sqrt{2} }{2}$

you can put the scalar in to get
