Diketahui vektor u=(5 -1), vektor v=(9 11), dan vektor

a. (14, 10) b. (6, 3) c. (-8, -7) d. (12, 19)

Pembahasan

Untuk menentukan:
a. u+v: 
   u = (5, -1)
   v = (9, 11)
   u+v = (5+9, -1+11) = (14, 10)

b. v+w:
   v = (9, 11)
   w = (-3, -8)
   v+w = (9+(-3), 11+(-8)) = (6, 3)

c. -u+w:
   -u = (-5, 1)
   w = (-3, -8)
   -u+w = (-5+(-3), 1+(-8)) = (-8, -7)

d. v-w:
   v = (9, 11)
   w = (-3, -8)
   v-w = (9-(-3), 11-(-8)) = (9+3, 11+8) = (12, 19)
