How would you determine whether the given vectors are orthogonal, parallel, or neither?

a. u= %26lt;-3,9,6%26gt;, v= %26lt;4,-12,-8%26gt;


b. u= i - j + 2k, v= 2i - j + k


c. u= %26lt;a, b, c%26gt;, v= %26lt;-b,a,0%26gt;





thanks for taking a look

Two vectors are orthogonal if their dot product is zero.


Two vectors are parallel if their cross product is zero.


It is neither if neither their dot product or cross product is equal to zero.
