- Need help with matrix multiplication: $ (aI + bJ)(cI + dJ)
(a) Using $ IJ = JI $, compute $ (aI + bJ)(cI + dJ) $ (b) Compare this with the multiplication of two complex numbers $ a + bi $ and $ c + di $, where $ a $, $ b $, $ c $ and $ d $ are real numbers linear-algebra

- Find all possible values of a parallel vector with equal magnitude
Well, if two vectors are parallel their cross product is zero There should only be one possible set of values for a vector with a fixed magnitude in 3 dimensions to be parallel to another one unless you are also considering antiparallel (imagine a fixed direction and rotating an arrow of fixed size)

- How to find perpendicular vector to another vector?
The dot product of two perpendicular vectors are always $0$ so if you $(ai+bj+ck)\cdot(di+ej+fk)=0$ you can solve for the different variables If you have one vector than the infinite amount of perpendicular vectors will form a plane that is perpendicular to the original vector If you know one or two of the coordinates of the desired
