Question

How do you find the inner product and state whether the vectors are perpendicular given `<5,-1>*<-3,6>`?

Answer 1

Dot product `=-21` and vectors are not perpendicular

Explanation:

Let the vectors be `vecu=(5,-1)`
and `vecv=(-3,6)`
Then the ot product or inner product is `vecu.vecv`
`=5*-3+6*-1=-21`
The vectors are not perpendicular as the dot product `!=0`
