AI Thread Summary
To manipulate the inequality 1/(n-2) < epsilon correctly, it is essential to establish that n > max(epsilon + 2, 1). The discussion clarifies that for positive epsilon, the condition 1/(n-2) < 1/epsilon leads to n - 2 > 1/epsilon. It is noted that since epsilon is typically a small positive number, 1/epsilon will generally exceed epsilon itself. Thus, the key takeaway is ensuring that n is sufficiently large to satisfy the inequality while maintaining epsilon as a small positive value.

so I have 1/(n-2). I have that n>max(epsilon+2,1). I need to get 1/(n-2) < epsilon. I know that 1/(n-2)<1/(epsilon+2-2)=1/epsilon. but 1/epsilon is not always less than epsilon. can you see any errors?

Epsilon is typically a small positive number that is much closer to 0 than it is to 1. Unless epsilon is negative, epsilon + 2 will be larger than 1.

1/(n - 2) < epsilon <==> n - 2 > 1/epsilon, making the reasonable assumptions that n > 2 and epsilon > 0.

If epsilon is small and positive, 1/epsilon is generally larger than epsilon.
 
I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks
Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
