In plane coordinates, how can one calculate the probability that any line is on lattice point?
If you add set theory grounds about solving this problem, I would be very thankful.

  • choosing depends on only random. I think that it would be 0. because in case that slope and y-intercept are e(exponential), it isn't on lattice point. cause irrational number set is larger than rational number set, I think that because of many irrational number, it would be 0.

  • Probability requires a probability distribution. There is no uniform probability distribution over the entire plane, so we have to choose something else. A random point in the square $[0,1]times[0,1],$ and a line at a random angle through that point, might be suitable. Are you familiar with Buffon's needle problem?

Is there any way to eliminate the singular point to solve this integral by hand or by approximations?

Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite 1 $$int_0^1 (1+(x^-p-1)^1-p)^frac1pdx, pin mathbbR, pge 1$$ I find that $x=0,1$ are singular points(discontinuous points of this integral), is there a way to eliminate those singular points to make sure that this integral can be calculated by hand or by Taylor approximations. In either cases, what are those steps of calculating the integral? calculus real-analysis analysis approximation share | cite | improve this question edited Sep 11 at 5:07 asked Sep 11 at 4:48 Mclalalala 126 8 1 What is $p$?
