👉 Rescue math is a mathematical technique used to solve problems involving exponential growth or decay, particularly when the initial conditions are far from equilibrium. It involves transforming these problems into a linear system by introducing a new variable, often called a "rescue variable," which represents the amount of a quantity being added back to the system. This transformation allows for the application of linear algebra methods, such as finding eigenvalues and eigenvectors, to solve complex exponential problems efficiently. By doing so, rescue math simplifies the process of determining the long-term behavior of systems that would otherwise be intractable with traditional methods.
