We’ll start by attempting to solve a couple of very simple In this chapter we will study ordinary differential equations of the standard form below, known as the second order linear equations: y″ + p(t)y′ + q(t)y= g(t). Homogeneous Equations: If g(t) = 0, then the equation above becomes. y″ + p(t)y′ + q(t)y= 0. It is called a homogeneousequation.

## The Navier–Stokes equations are nonlinear partial differential equations in the general case and so remain in almost every real situation. In some cases, such as one-dimensional flow and Stokes flow (or creeping flow), the equations can be simplified to linear equations.

This type of equation occurs frequently in various sciences, as we will see. If a particular solution to a differential equation is linear, y=mx+b, we can set up a system of equations to find m and b.

### Linear equations include dy/dt = y, dy/dt = –y, dy/dt = 2ty. The equation dy/dt = y*y is nonlinear.

Solving this second order non-linear differential equation is a practically impossible. This is where the Finite Difference Method comes very handy. It will boil down to two lines of Python! Let’s see how.

### Theorem: Existence and Uniqueness for First order Linear Differential Equations. Let \[ y' + p(x)y = g(x) \] with \[ y(x_0) = y_0 \] be a first order linear differential equation such that \(p(x)\) and \(g(x)\) are both continuous for \(a < x < b\). Then there is a unique solution \(f(x)\) that satisfies it.
