In our world things change, and describing how they change often ends up as a Differential Equation.
Differential Equations can describe how populations change, how heat moves, how springs vibrate, how radioactive material decays and much more. They are a very natural way to describe many things in the universe. In order for these equations to be useful, we need to solve them. When we solve them, we determine what function or functions satisfy the equation.
So let's experience the magic of these equations!
