Question

Diketahui segitiga ABC dengan A (5,3,-1) B (-2,4,3) C (-1,-5,2) rusuk garis berarah Bc mewakili vektor u dan rusuk garis nerarah BA mewakili vektor v.hitung u-v

Answer 1

A (5,3,-1)

B (-2,4,3)

C (-1,-5,2)

BC=u

C-B=u

(-1,-5,2)-(-2,4,3)=u

(1,-9,-1)=u

BA=v

A-B=v

(5,3,-1)-(-2,4,3)=v

(7,-1,-4)=v

u-v=(1,-9,-1)-(7,-1,-4)

=(-6,-8,-3)
