It's supposed to be an easy question, but I'm not a math major.

Evaluate lim x-->0+ (√(9 + 17lnx + 9ln^2x) - 3√(1 + lnx + ln^2x)) , if the limit exists
 
Physics news on Phys.org
What happens to the value of ln(x) as x goes to zero from above? Once you answer that, then think about 9+17ln(x). What is that approximately equal to for x very close to 0?
 
K thanks. I think I got it now.
 
You got zero right?

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...
