What are the resultants of the vector product of two given vectors given by `vec(A) = 4 hat(i) - 2 hat(j) + hat(k) and brc(B) = 5 hat(i) + hat(j) - 4 hat(k)` ?

Explanation

`vec(A) = 4hat(i) - 2 hat(j) + hat(k)`
`vec(B) = 5 hat(i) + 3 hat(j) - 4 hat(k)`
`vec(A) xx vec(B) = |{:(i," "j,k),(4,-2,1),(5," "3,-4):}|`
`= i (8 - 3) + j [ 5 - (-16)]+ k [ 12- (-10)]`
`= 5 hat(i) + 21hat(j) + 22 hat(k)`
