 Mar7 comment What is exponentiation? isn't $a^{\pi} < max(a^3,a^4)$ enough to say it's convergent (since it's also increasing with your decomposition) Feb20 revised Calculate interests deleted 57 characters in body Feb20 revised Calculate interests added 55 characters in body Oct26 awarded Popular Question Sep22 awarded Tumbleweed Sep15 asked Removing density functions 'offset' Jul1 awarded Popular Question Dec3 awarded Promoter Dec3 revised Calculate interests deleted 8 characters in body Dec2 comment Calculate interests I'm currently googling to know which option is commonly used, thx Dec2 comment Calculate interests yes r: yearly interests of the loan and m: monthly payback, @AndréNicolas I have edited the question with what you suggested can you have a look? Dec2 revised Calculate interests added 917 characters in body Dec2 comment Calculate interests I don't agree, at the end of first year, the loan is N less 12 paybacks, and you add the interests Dec2 comment Calculate interests ok else, to me, for the amount at beginning of years: $N_y = N_{y-1} - 12m + r(N_{y-1}-6m)$ no? (you have put $12m$ also multiplied by r) Dec2 comment Calculate interests seems x and y are mixed, it's V(x,b... ) above? Dec2 comment Calculate interests @AndréNicolas I thought when you do a loan, the interests were added at the end of the year only, but it's probably each months, it would increase slightly the result. yes r is the nominal interest rate (e.g. 2.5%), @ Limitless thx trying to understand it Dec1 revised Calculate interests edited title Dec1 asked Calculate interests Nov17 revised Integer sequence comparison, binomials Vs power added 4 characters in body Jun29 comment combinatorics counting sets with a one element having values in another set yes i know, it's a data indexation problem, and the solution in the post scales better than putting all elts inline
