The video introduces modeling with differential equations, focusing on population growth. It defines variables and sets up a basic model, explaining the proportionality of growth rate to population size. The video then demonstrates solving a separable differential equation through integration, leading to a general solution. The process is linked to familiar exponential functions, providing a deeper understanding of the underlying logic.
