`Calculating a Dot Product
`
`Dot product requires two sequences of equal length, e.g.,
`
`Sequence A = [a
`
`, a
`2
`
`, a
`3
`
`, a
`4
`
`1
`
`]
`
`Sequence B = [b
`
`, b
`2
`
`, b
`3
`
`, b
`4
`
`1
`
`]
`
`Dot product multiplies corresponding components of
`each sequence, and then sum all the products, i.e.,
`
`a
`1
`
`×b
`
` + a
`2
`
`×b
`2
`
` + a
`3
