Hi guys, I have a question... I have this formulae: log(1  DC) N =  log(1  p) I can find N if I have DC and p. But I can't figure out how to find DC if I have N and p. Is that possible? Cheers!

log(1  DC) = N(log(1  p)) Assuming base 10... 1  DC = 10^[N(log(1  p))] etc. Another approach uses the fact that log(1  DC)/log(1  p) = log(1  DC) using base (1  p).

log(1  DC) = N log(1  p) = log((1  p)^N), so DC = 1  (1  p)^N.
