👉 Lifetime math is a branch of mathematics that extends traditional mathematical analysis to consider functions and their properties over infinite time intervals, rather than just finite ones. It involves studying the behavior of functions as time approaches infinity, often using tools from calculus and analysis to understand limits, convergence, and stability over an unbounded domain. This approach is crucial in fields like physics, engineering, and economics, where phenomena are often modeled over extended periods or infinite horizons. Lifetime math provides a framework for analyzing long-term trends, asymptotic behaviors, and the stability of systems, offering insights into how functions evolve and behave as time stretches out infinitely.
