Find the angle between the given vectors . Round to the nearest tenth of a degree.

1) u= -3i +6j ,v=5i + 2j

2) u= i -j , v=2i +3j

Use the dot product to determiine wheter the vectors are parallel, orthogonal , or neither .

1) v = 2i +j, w = i-2j

2) v = 4i-j , w=8i-2j

3) v= 3i +3j , w=3i -2j

Find proj w v

1) v = 2i +3j . w = 8i- 6j

2) v= 2i -3j . w =-3i +j

1) u= -3i +6j ,v=5i + 2j
