Math 136 Assignment 3 Due: Wednesday, Jan 25th 1. Let ~u = 2 1 3 and ~v = 1 - 1 1 . Calculate proj ~v ~u and perp ~v ~u . 2. Let ~u = 1 2 - 3 and ~v = 1 0 1 . Calculate proj ~v ~u and perp ~v ~u . 3. Find the projection of ~v = 1 1 2 onto the plane S = span 1 - 2 1 , - 2 1 - 2 . 4. Let P be the plane in R 3 with vector equation ~x = s 1 0 - 1 + t 2 2 - 1 . Find the projection of ~v = 2 3 1 onto P . 5. Prove that if { ~x,~
