Question

O calculo é sobre vetores:

Sendo A = (2,0,1), B = (0,3,-2), C = (1,2,0), determinar D = (x,y,z), tal que BD= AB + CB.

Answer 1

(x-0,y-3,z-(-2))=(0-2,3-0,-2-1)+(0-1,3-2,-2-0)
(x-0,y-3,z+2)=(-2,3,-3)+(-1,1,-2)
(x-0,y-3,z+2)=(-3,4,-5)
x-0=-3     x=-3
y-3=4      y=7
z+2=-5    z=-7

D=(-3,7,-7)
