Question

resuelve las siguiente operaciones
a. u+v
b.u-v
c. k (2u+v)
d. -k (u.v)

Answer 1

Respuesta:

u + v = (1 + 2, 2 + (-1) ) = (3 , 1)

u - v = (1 - 2 , 2 - (-1)) = (-1 , 3)

3u - v = (3 , 6) - (2, -1) = (3 - 2, 6 - (-1)) = (1 , 7)

(1 / 2)u + v = ( 1 / 2 , 1 ) + ( 2 , -1) = ((1 / 2) + 2 , 1 + (- 1)) = (5 / 2 , 0)
