Question

Find the vector and parametric equations of the plane containing the points A (1,0,3) , B ( 2,-3,1) and C (3,5,-3)
my question is, does it matter if i use vector AB and vector BC instead of vector AB and vector AC

cuz it gives different vector and parametric equations

Answer 1

it's very important to use the vectors from the same point...so you can use AB and AC or BA and BC or CA and CB....it doesn't matter in which order, but from the same starting point

Answer 2

thanks! i get it

Answer 3
