Question

Let v1=(2,-6) and v2= (-4,7)

a. compute |v1| and |v2|.

b. compute the unit vectors in the direction of |v1| and |v2|.

c. Draw and lable v1,v2, v1+v2


plz help if you can :)

Answer 1

just use pythogorean theorem for a

|v1| = sqrt(2^2+6^2)

Answer 2

for b wouldn't it just be v1/|v1| and v2/|v2|

Answer 3

it is horrible but nvrmnd it :P
