Any one happened to know why they are allowed to write z= k in 8B.

I think it is because z is not defined in the x3 equations so it should be a constant? , found my own explanation a bit strange.

Its independant i think. For any z x,y are zero.

I am nkt definate as I havent looked in detail.

so does that mean z = k for the other eigenvectors ?

I think it's because you have -2x+y=0, x-2y=0, and -x=0 and no equation involving z. This is something you kinda just need to memorise/know.

We couldn't conclude from this that z=k for the other eigenvectors, we would have to calculate it each time.

No, fp3 is the right choice of subject lol. D2 is easy but the methods are mind blowingly long. -_-' and definitions are so hard to remember. Fp3 is nice lol.

UCL for mathematics. You?
