Question

i need help with determining where the vector is parallel or orthogonal

Answer 1

whether*

Answer 2

You can determine orthogonality by taking a dot product of the two vectors. If the dot product is 0, then it is orthogonal.

Answer 3

If the two vectors are parallel, suppose v1 and v2 are parallel, then \[v_{1} = c \times v_{2} \]

Answer 4

This means that you can multiply the vector v2 by some scalar value to get v1 if they are parallel.
