Question

Determine whether u and v are orthogonal, parallel, or neither. u=(1,-7) v=(-42,3)

Answer 1

u=1-j7, and v=-42+j3

Answer 2

Dot product is not zero and both of them are not similar when multiplied by any scalar so they are neither orthogonal nor parallel

Answer 3

\[u*v= (i*i)(j*j)\]

Answer 4

for parallel vectors u*v=|u||v|

Answer 5

|u|=\[\sqrt{a^2+b^2}\]

Answer 6

neither
