The expression "∞/∞" represents an indeterminate form in mathematics. It occurs when both the numerator and denominator approach infinity, making it unclear what the value of the expression is. This situation often arises in calculus, particularly in limits, where it requires further analysis to determine a specific value. To resolve "∞/∞," mathematicians typically use techniques such as L'Hôpital's Rule or algebraic manipulation. These methods help simplify the expression or find a limit that can provide a meaningful result. Understanding this concept is essential for studying advanced topics in calculus and real analysis.
