05.06.2020 · Linear ordinary differential equation An ordinary differential equation (cf. Differential equation, ordinary) that is linear in the unknown function of one independent variable and its derivatives, that is, an equation of the form $$ \tag {1 } x ^ { (} n) + a _ {1} ( t) x ^ { (} n- 1) + \dots + a _ {n} ( t) x = f ( t) , $$

General and Standard Form •The general form of a linear first-order ODE is 𝒂 . 𝒅 𝒅 +𝒂 . = ( ) •In this equation, if 𝑎1 =0, it is no longer an differential equation and so 𝑎1 cannot be 0; and if 𝑎0 =0, it is a variable separated ODE and can easily be solved by integration, thus in this chapter

Such an equation is an ordinary differential equation (ODE). A linear differential equation may also be a linear partial differential equation (PDE), if the unknown function depends on several variables, and the derivatives that appear in the equation are partial derivatives.

The solution process for a first order linear differential equation is as follows. ... Multiply everything in the differential equation by μ(t) μ ...

Linear just means that the variable in an equation appears only with a power of one. So x is linear but x2 is non-linear. Also any function like cos(x) is non ...

Differential equations are perhaps the most successful method discovered for modeling natural phenomena. Within this vast field, linear ordinary differential equations occupy a central role: in numerous examples the model is a linear system of equations, whereas in other cases a linear approximation is the essential tool for analyzing local behavior.
