Summation Calculator
Category: Sequences and SeriesCalculate sums using mathematical notation including arithmetic series, geometric series, and custom functions. Perfect for students, mathematicians, and anyone working with sequences and series.
Summation Details
- Arithmetic Series: \( S = \frac{n}{2} \times (2a + (n - 1)d) \)
- Geometric Series: \( S = a \times \frac{1 - r^n}{1 - r} \), for \( r \ne 1 \)
- Power Series: \( S = \sum a \cdot n^k \)
- Harmonic Series: \( S = \sum \frac{1}{n} \)
- Custom Function: \( S = \sum f(n) \)
