Diketahui vektor u = 4i + 6j dan v = 7i - 24j. tentukan: a). u + v b). |u| c). |v| d). |u + v|
naidhaf
A. u+v = 11i-18j b. akar 4 kuadrat + 6 kuadrat = akar 16+36 = akar 52 c. akar 7 kuadrat + (-24) kuadrat = 49+576 = akar 725 = 5 akar 29 d. akar 11 kuadrat + (-18) kuadrat = 121+ 324 = akar 445
b. akar 4 kuadrat + 6 kuadrat = akar 16+36 = akar 52
c. akar 7 kuadrat + (-24) kuadrat = 49+576 = akar 725 = 5 akar 29
d. akar 11 kuadrat + (-18) kuadrat = 121+ 324 = akar 445
