Domain-specific

• Divisor Function
  • NIST's Digital Library of Mathematical Functions uses this definition and identifies \(\sigma_0(n)\) with the divisor-counting function and \(\sigma_1(n)\) with the sum of divisors.

• Riemann sum
  • The move from For \(f(x)=x\) on \([0,1]\), equal-width right-endpoint sums are \(n^{-2}\sum_{i=1}^n i=(n+1)/(2n)\), which approach \(1/2\). to A time-varying rate sampled over short intervals can be multiplied by each interval duration and summed to approximate total accumulation. demonstrates that continuity.
