## anonymous one year ago i need help with determining where the vector is parallel or orthogonal

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

3. anonymous

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

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