### 10.11 Products of vectors

Let $a=\left({a}_{1},{a}_{2},{a}_{3}\right),\text{?}b=\left({b}_{1},{b}_{2},{b}_{3}\right)$, and $c=\left({c}_{1},{c}_{2},{c}_{2}\right)$ be arbitrary vectors, and $i,j,k$ be the set of orthogonal unit vectors in terms of which the components of $a,b$, and $c$ are expressed. Two different products involving pairs of vectors are defined, ...
