It can be helpful to classify a differential equation, so that we can predict the techniques that might help us to find a function which solves the equation. Two classifications are the order of the equation -- (what is the highest number of derivatives involved) and whether or not the equation is linear Linearity is important because the structure of the the family of solutions to a linear equation is fairly simple. Linear equations can usually be solved completely and explicitly. Determine whether or not each equation is linear: 2nd order Nonlinear 1. "-y + y² = 0 2nd order Linear 4th order Linear 2. 3. d²y dt² + sin(t + y) = sint d'y d³y d²y dy + + dt4 dt3 dt² dt d²y 2nd order Nonlinear 4. (1+²) +t dy dt2 dt + = 1 +y=e
