To solve for them initial conditions must be provided.If initial conditions are provided use them along with the general solution to solve an algebraic system of equations for the constants. Integrability has a specific meaning for certain differential equations arising in geometry, but I'm not sure if it has a broader meaning for more general differential equations. Plug eigenvalues back in and obtain eigenvectors. An ordinary differential equation (ODE) is an equation containing an unknown function of one real or complex variable x, its derivatives, and some given functions of x.The unknown function is generally represented by a variable (often denoted y), which, therefore, depends on x.Thus x is often called the independent variable of the equation. Differential Equations - Objective Section Maps Objective Section Maps (Mathematics) Chapter 9: Differential Equations Here is an Educart exclusive for students and teachers!
