### Mathematical notes 12--Ordinary differential equations and discrete variables _ ordinary differential equations

Ordinary differential equations Derivative that contains an unknown function, such as The equation is a differential equation. In general, the equation that represents the relationship between the derivative of an unknown function, an unknown function, and an independent variable is called a differential equation. The unknown function is a unary function, called the ordinary differential equation, and the unknown function is called the partial differ
