Homework Statement



solve: y'=(x+y-1)/(x-y-2) i.e

Homework Equations





The Attempt at a Solution



let y=vx
thus
y'=v'x+v

by substitution:

v'x+v=(1+y/x-1/x)/(1-y/x-2/x)=(1+v-1/x)/(1-v-2/x)

v'x=(1-1/x+v^2+2v/x)/(1-v-2/x)

still can't separate the variables...any ideas?

thanksx

thanks dick does work!
 
Uh, are you sure? I tried it again after I posted, and realized I'd made a mistake and deleted the post so it wouldn't confuse anyone. Just double check, ok?

Thread 'Use greedy vertex coloring algorithm to prove the upper bound of χ'
Hi! I am struggling with the exercise I mentioned under "Homework statement". The exercise is about a specific "greedy vertex coloring algorithm". One definition (which matches what my book uses) can be found here: https://people.cs.uchicago.edu/~laci/HANDOUTS/greedycoloring.pdf Here is also a screenshot of the relevant parts of the linked PDF, i.e. the def. of the algorithm: Sadly I don't have much to show as far as a solution attempt goes, as I am stuck on how to proceed. I thought...
