1. The problem statement, all variables and given/known data

The problem is Exercise 8

[PLAIN]http://postimage.org/image/6kpizm8dj/ [Broken][/PLAIN]

2. Relevant equations

in picture

The hint says "follow the steps as in the previous exercise, using the properties of (phi 1) and (phi 2) as already established".

3. The attempt at a solution

I tried substituting in phi 1 and phi 2 to solve for beta and gamma but that didn't work.

What you show defines phi1 and phi2 in terms of u1 and u2 but does not say what u1 and u2 are. Also #7 asks you to "Show that $\alpha= -(\phi_1, u_2)$" but you give no definition of $\alpha$.
