 P: 736 Do you guys know any free plotters? (or the sites/links to them) Any free program/software that can plot sequences? Such as A_n = sum(mod(floor(n/p^k),p)*(p/q)^k,k,0,n) A_n = sum(seq(mod(floor(n/p^k),p)*(p/q)^k,k,0,n)) Which is $$A_n = \sum\limits_{k = 0}^n {\bmod \left( {\left\lfloor {\frac{n}{{p^k }}} \right\rfloor ,p} \right)\left( {\frac{p}{q}} \right)^k }$$
