Does it help to remember that if the dot product of two vectors is zero, then they are orthogonal (perpendicular).
Sorry, I'm in the same boat you are it seems, we just started vectors and I'm wading my way through the material.
I really need help on vectors were you have to find a perpendicular vector. I have 2 questons that are really confusing me:
1. Find a vector which is perpendicular to both a and b
a =
b =
2. Show that lines L1 and L2 are perpendicular to each other.
L1:
L2:
Thank You, this part of vectors is really confusing me

Hello, Stylis10!
A vector perpendicular to two vectors is their cross product.1. Find a vector which is perpendicular to both
. .
. .
Two vectors are perpendicular if their dot product is zero.2. Show that lines are perpendicular.
We have: .
. . Therefore: .
