Question

Determine if u = [2, 7, −1], v = [5, −3, 2] and w = [9, 11, 2] are coplanar

Answer 1

Any three points or vectors determine a unique plane, so u v and w are coplanar

Answer 2

since u v and w are all in the same plane

Answer 3

thanks

Answer 4

i need to show my work...im using the u=sv+tw method

Answer 5

and i cant find the values of s and t

Answer 6

hmm not familiar with that method

I think you just need to take the cross product of any two vectors to find the normal to the plane

Answer 7

that should determine the equation of the plane

Answer 8

okay thnks
