Ratio Test Calculator
Advanced mathematical tool for analyzing infinite series convergence using the ratio test calculator method. Determine series behavior with precision and comprehensive step-by-step analysis.
Understanding the Ratio Test Calculator
The ratio test calculator is an essential mathematical tool used to determine the convergence or divergence of infinite series. This powerful method, also known as d'Alembert's ratio test, examines the limit of the ratio between consecutive terms in a series to establish its behavior.
Convergence Criteria
- If L < 1: Series converges absolutely
- If L > 1: Series diverges
- If L = 1: Test is inconclusive
Mathematical Formula
L = limn→∞ |an+1 / an|
Where an represents the nth term of the series
