Introduction

The order of a differential equation is determined by the highest-order derivative. The higher the order of the differential equation, the more arbitrary constants need to be added to the general solution. A first-order equation will have one, a second-order two, and so on. The degree of a differential equation, similarly, is determined by the highest exponent on any variables involved.

Examples:

  • Failed to parse (syntax error): {\displaystyle y'' + xy' – x^3y = \sin{x} } is of order 2 because the highest-order derivative, , is of order 2.
