About 9. Mathematical Modelling with Differential Equations

Differential equations express relationships between functions and their derivatives, making them the natural language for modeling dynamic systems in nature and engineering. Instead of solving for a number, students solve for an unknown function that satisfies conditions involving its own rate of change, such as population growth, radioactive decay, or Newton’s law of cooling. This chapter introduces separable equations and first-order linear equations as foundational models that capture how quantities evolve over time.

Mathematical modeling with differential equations emphasizes translating real-world phenomena into mathematical form and interpreting solutions in context. Students learn to incorporate initial conditions, analyze equilibrium solutions, and use direction fields to visualize behavior even when exact solutions are difficult to obtain. This chapter bridges pure mathematics and applied science, showing how calculus provides predictive power for understanding everything from epidemic spread to electrical circuits.
