Question

Let v1 = (-6,4) and v^2 = (-3,6). Compute the following V^1 * V^2

Answer 1

It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of ($x_{1}$; $y_{1}$) and ($x_{2}$; $y_{2}$) is $x_{1}$ * $x_{2}$ + $y_{1}$ *  $y_{2}$ = (-6)*(-3)+4*6=18+24=42
