Tavavõrrandid

Tavavõrrandid, often translated as "ordinary differential equations" in English, are mathematical equations that involve an unknown function of one independent variable and its derivatives. The term "ordinary" distinguishes them from partial differential equations, which involve functions of multiple independent variables and their partial derivatives. The order of a differential equation is determined by the highest derivative of the unknown function present in the equation. For instance, an equation containing a second derivative but no third or higher derivatives is a second-order differential equation.

The primary goal when solving a tavavõrrand is to find the unknown function that satisfies the equation. Solutions can be expressed as explicit functions, where the dependent variable is isolated on one side of the equation, or implicit functions, where the relationship between variables is defined by an equation that cannot be easily rearranged to solve for the dependent variable explicitly. Tavavõrrandid are fundamental tools in various scientific and engineering disciplines. They are used to model a wide range of phenomena, including the motion of objects, the growth of populations, the flow of heat, and the behavior of electrical circuits. The study of tavavõrrandid forms a significant branch of mathematics known as differential equations.
