Nonlinear System
A nonlinear system is a set of mathematical equations where the relationship between variables isn't straight or directly proportional. Unlike linear systems, where changes in inputs produce predictable, proportional outputs, nonlinear systems can behave complexly—producing multiple outcomes, oscillations, or chaos. These systems are common in nature and engineering, such as weather patterns, ecosystems, and financial markets. Understanding nonlinear systems helps us model and predict behaviors that aren't straightforward, capturing the intricate dynamics of real-world phenomena.
