Question

the following vector v = 9i + 8j, w = 8i + 9j

State whether the vectors are parallel, orthogonal, or neither.

is it neither?

Answer 1

first find the dot product of V and W

Answer 2

144

Answer 3

yeah
now two vectors a and b are orthogonal if dot product of a and b =0
so are they orthogonal?

Answer 4

no

Answer 5

now find the cross product of V and W

Answer 6

can u find the cross product i mean (VXW)

Answer 7

i dont know how to do cross product yet

Answer 8

so its nor parallel as the cross product is not equal to 0
