comment Getting the sequence $\{1, 0, -1, 0, 1, 0, -1, 0, \ldots\}$ without trig?
@Anixx he needs to be able to enter it into a calculator, presumably without trigonometric functions. Most calculators can evaluate exponents, this should be fine.

comment Biased lower bounded random walk
Hmm... Since there is a higher probability of going up than down (0.6 to 0.4), it seems that in the long run, it will tend to increase. That's all I can figure out. Nice question! Also, what do you mean by lower bounded here?
