Nonlinear Equations

Nonlinear equations are mathematical expressions where the relationship between variables isn’t straightforward; they don't create a straight line when graphed. Instead, their graphs can be curves, circles, or more complex shapes. This nonlinearity means that small changes in input can result in large changes in output, making them especially common in real-world scenarios, like predicting population growth or modeling the weather. Unlike linear equations, which have a constant rate of change, nonlinear equations can involve various factors that interact in complex ways, making them more intricate but often more realistic in describing natural phenomena.
