Question

Prove that A= 4i +3h+k and B=12i+9j+3k ar parallel to each other

Answer 1

they are parallel

by using equating the co-efficients method. i1/i2=h1/h2=k1/k2

if they are equal they will be definitely parallel

i1/i2 =4/12=1/3

h1/h2=3/9=1/3

k1/k2=1/3=1/3

they are equal that's why they are parallel
