Key Concepts

Sequence Convergence

This concept involves determining whether the terms of a sequence approach a unique value (the limit) as the index increases. Analyzing convergence typically requires evaluating the behavior of the general term of the sequence as the index goes to infinity, and applying limit definitions and theorems to decide between convergence and divergence.

Limit of Composition of Functions

When a sequence is defined by a composition of functions, its limit can often be found by composing the limits of the individual functions, provided the outer function is continuous at the limit point of the inner function. This stepwise approach simplifies the analysis by dealing with each function separately.

Growth Behavior of the Natural Logarithm

The natural logarithm function, ln(n), increases without bound as its argument grows, although it does so relatively slowly compared to polynomial or exponential functions. Recognizing that ln(n) diverges to infinity is essential when it is used as the inner function in a composite limit evaluation.

Asymptotic Behavior of Inverse Trigonometric Functions

Inverse trigonometric functions, such as arctan, have horizontal asymptotes that they approach as their argument tends to positive or negative infinity. Understanding these asymptotic properties allows one to determine the limit of a sequence where an inverse trigonometric function is applied to a variable growing without bound.
