Nonlinearity refers to a relationship between variables where a change in one variable does not result in a proportional change in another, often leading to complex and unpredictable behavior. It is a fundamental concept in various fields, indicating systems where outputs are not directly proportional to inputs, requiring advanced mathematical tools for analysis and understanding.

relationship between variables

Proportional change refers to the relative change in a variable, expressed as a ratio or percentage, compared to its original value. It is a fundamental concept in mathematics and economics, used to analyze growth rates, elasticity, and comparative statics.

Complex Behavior

Unpredictable behavior refers to actions that are not easily anticipated due to a lack of consistent patterns or external cues. This can arise from complex systems, individual cognitive processes, or environmental factors that introduce variability and uncertainty.
