Homework Equations
The Attempt at a Solution
This is the steps i took
1. found basic solution for U, 3 by 4, matrix to find U-perp
1. found basic solution for V, 3 by 4, matrix to find V-perp
3. Then i put V and U - perpendicular vectors to gether and got basic solutions with dim = 2 and 2 basic solutions.
than i did gram schmitt to find othogonal basic of those two
F1 = X1
F2 = X2 - {(F1 dot X2) / ||F1||2}F1
where did i went wrong
