# Thread: Expansion of Vector Two Norm

1. ## Expansion of Vector Two Norm

Hello,

This seems like it should be easy, but I don't know the verbiage to search for a method to learn. I am attempting to expand a vector two norm of a vector equation.

R is a 3x3 matrix
p is a 3x1 vector
t is a 3x1 vector
q is a 3x1 vector

||Rp+t-q||^2

The first step is knowing that the above equals:
(Rp+t-q)^Transpose(Rp+t-q)

2. ## also...

Should have mentioned that R is an element of SO(3)
