"...What if all you had to do to solve an ODE were just to write it down? That is the line we will follow in this book. Our emphasis is not just on the mathematics of ODEs, but on how the solutions behave. Do they blow up, decay, oscillate? re there rapid transitions where they flip from one state to another? Does the behavior change if a coefficient is perturbed or a new term is added? And how can such variety be deployed to explain the world around us? We shall not just talk about these matters but explore them in action..."
