Sum of Powers of Divisors
Sum of Powers of Divisors
This Demonstration plots the values (n)=, where indicates the sum is taken over the divisors of , ranges from 1 to , and you control the continuous exponent . When , (n)=τ(n) gives the number of divisors of . When , (n)=σ(n) gives the sum of the divisors of .
