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
