Find area of a parallelogram with vertex at the origin and with the given vectors as edges: $i +3j - 5k$ and $i +7j - k.$
So matrixes for me take the longest time to put in LaTeX so im just asking if im logic for this is right.
I would let the first vector be b, and the 2nd vector be c. Then I would compute
$\| b \times c \|.$
Is that right?
