Question

Drawing such a blank!

Find a vector, unit in length, that is parallel to the plane 3x-y+7z = 5 and perpendicular to the vector <1,-1,2>

Answer 1

Normal vector would be <3,-1,7>

Answer 2

So any vector perpendicular to this normal would be parallel to the plane

Answer 3

yep so you want to find a vector that is perpendicular to both <3,-1,7> and <1,-1,2>

Answer 4

cross product! -_-

Answer 5

you will compute the cross product of those two vectors, yep you beat me to it lol

Answer 6

Thank you jim! lol I guess I just needed someone to say it differently...thats enough math for today! lol
