In the vast realm of mathematics, the study of infinite series has captivated the minds of scholars for centuries. These intriguing mathematical constructs, composed of an infinite number of terms, possess remarkable properties that govern their behavior. Among these properties, convergence and divergence stand out as fundamental concepts that determine the nature of a series.
A convergent series is one whose partial sums approach a finite limit as the number of terms tends to infinity. This limit is known as the sum of the series. On the other hand, a divergent series is one whose partial sums do not approach a finite limit, causing the series to oscillate or grow without bound.
Understanding the convergence or divergence of a series is crucial for various mathematical applications. It enables us to determine whether a series represents a finite value or not, and it paves the way for exploring deeper properties and applications of the series.

The primary objective of a convergent or divergent calculator is to determine the convergence or divergence of an infinite series. This seemingly simple task belies a world of mathematical intricacies, as the behavior of infinite series can be subtle and elusive.
To achieve this, the calculator employs a range of convergence tests, each tailored to specific types of series. These tests leverage mathematical principles to analyze the behavior of the series’ terms and deduce whether they approach a finite limit or diverge to infinity.
Some of the most commonly used convergence tests include:
 Ratio Test: This test compares the absolute value of the ratio of consecutive terms in the series to a constant. If the limit of this ratio is less than 1, the series is absolutely convergent, meaning it converges absolutely and conditionally.
 Root Test: Similar to the Ratio Test, the Root Test examines the limit of the nth root of the absolute value of the series’ terms. If this limit is less than 1, the series is absolutely convergent.
 Integral Test: This test utilizes integration to determine the convergence of a series. If the improper integral of the series’ terms converges, then the series itself converges.
 Comparison Test: This test compares a given series to a series with known convergence or divergence. If the given series’ terms are always greater than or equal to the terms of the convergent series, then the given series diverges. Conversely, if the given series’ terms are always less than or equal to the terms of the divergent series, then the given series converges.
The calculator applies these tests systematically, selecting the most appropriate test based on the characteristics of the input series. It then presents the result of the test, clearly indicating whether the series is convergent or divergent.
