 Apr 15 awarded Tumbleweed Apr 14 comment Approximate $\log(1-e^x)$ where $x<0$ do you want to approximate it for polynomials of $n$ degree? The Taylor expansion seems to work for exponential approximation.

Apr 4 comment Finding all lattice point in bounded region @hardmath I found the inequality by adding all null spaces of the equality relation. Adding particular solution to null spaces such that all elements of solutions are greater than zero. Apr 1 revised Finding all lattice point in bounded region added 813 characters in body; edited tags Apr 1 comment Finding all lattice point in bounded region @hardmath I don't know. I was given $n=8$. I am assuming $n\le10^3$. Anyway this came from coin change problem constrained to exact number of steps (coins). I modelled into $AX = B$ and trying to find all possible particular solutions for which $x_i \ge 0$ where $(x_i)^T = X$. Apr 1 comment Finding all lattice point in bounded region @hardmath I need the list of points :S Is there any other way where I can avoid looking all points in hypercuboid made by the intercepts of first inequality? Apr 1 comment Finding all lattice point in bounded region @hardmath edited the question. I think this is related to the Mixed Integer Linear programming. I don't have any function to minimize or maximize. Just need the lattice points. :( Apr 1 revised Finding all lattice point in bounded region added 26 characters in body Apr 1 revised Finding all lattice point in bounded region added 3 characters in body Apr 1 comment Finding all lattice point in bounded region IDK if it's correct place for asking. I couldn't think anywhere else other than SO and M.SE. Please forgive me if it was inappropriate.
