How to Use Harmonic Series Calculator
The Harmonic Series Calculator sums the first n reciprocal terms. It is a simple way to explore harmonic numbers and the slow divergence of the harmonic series.
- Enter a positive integer n for the number of terms.
- Read the harmonic sum shown as the primary result.
- Use the last-term detail to see the smallest fraction included in the calculation.
- Try larger n values to observe how the series keeps growing slowly instead of settling to a fixed limit.
Formula & Theory - Harmonic Series Calculator
The Harmonic Series Calculator uses the following formula or calculation model:
H(n) = 1 + 1/2 + 1/3 + ... + 1/n
H(n) = Σ(1/k), for k = 1 to nThe harmonic series adds reciprocals of positive integers. Although each new term becomes smaller, the infinite series diverges. For finite n, the calculator loops from 1 through n and adds 1/k each time. This makes it a useful numerical demonstration of slow divergence and approximation behavior.
Assumptions and Limits
Very large n values are capped for browser responsiveness, and floating-point arithmetic may introduce tiny rounding differences.
