This is the problem of determining a curve on which a weighted particle will fall to a fixed point in a fixed amount of time, independent of the starting point. Lagrange solved this problem in and sent the solution to Euler. Both further developed Lagrange's method and applied it to mechanics , which led to the formulation of Lagrangian mechanics. Contained in this book was Fourier's proposal of his heat equation for conductive diffusion of heat. This partial differential equation is now taught to every student of mathematical physics. Example[ edit ] For example, in classical mechanics , the motion of a body is described by its position and velocity as the time value varies. Newton's laws allow these variables to be expressed dynamically given the position, velocity, acceleration and various forces acting on the body as a differential equation for the unknown position of the body as a function of time. In some cases, this differential equation called an equation of motion may be solved explicitly.

Sturm-Liouville Transforms An example of modelling a real world problem using differential equations is the determination of the velocity of a ball falling through the air, considering only gravity and air resistance. The ball's acceleration towards the ground is the acceleration due to gravity minus the acceleration due to air resistance.

Gravity is considered constant, and air resistance may be modeled as proportional to the ball's velocity. This means that the ball's acceleration, which is a derivative of its velocity, depends on the velocity and the velocity depends on time. Finding the velocity as a function of time involves solving a differential equation and verifying its validity. Types[ edit ] Differential equations can be divided into several types.

Apart from describing the properties of the equation itself, these classes of differential equations can help inform the choice of approach to a solution. This list is far from exhaustive; there are many other properties and subclasses of differential equations which can be very useful in specific contexts.

Ordinary differential equations[ edit ] Main articles: Ordinary differential equation and Linear differential equation 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. The term "ordinary" is used in contrast with the term partial differential equation , which may be with respect to more than one independent variable.

Linear differential equations are the differential equations that are linear in the unknown function and its derivatives. Their theory is well developed, and, in many cases, one may express their solutions in terms of integrals.
