Observe that the differential equation alone does not define a unique solution; we also need an initial condition or other conditions. A plot of all trajectories, i.e., all solutions of the ODE (1.1) in the (t, u)-plane will result in a graph that is totally black since there are ...

A differential equation is essentially an equation that contains derivatives of a function, say, {eq}\frac{dy}{dx} {/eq}, where {eq}y = y(x) {/eq}. For example, {eq}\frac{dy}{dx} = 2y {/eq} is a differential equation; it relates the function with its derivative....

Since a rule like this is written with partial derivatives, we call it a partial differential equation. This has the funny result that to an outsider, the name sounds like a tamer version of ordinary differential equations, when to the contrary partial differential equations tend to tell a much...
