Differential Equations
1. Type
Ordinary Differential Equations
ex ) y" + y' = 0 , y" + 7 x( y' ) ^3 = 3x , ...
Partial Differential Equations
ex )
2. Linearity
Linear Differential Equations
ex) y" + xy' = 7x, 8y"' + 3y' = xy, ...
Nonlinear Differential Equations
ex) (y"")^19 + (y")^ 30 - xy = 30x, ...
3. Order
1st, 2nd, 3rd, ... , n-th Order Differential Equations
ex)
y' + y^3 = 0 -> 1st order differential equation
(x^50)y" + (y')^300 + y = x -> 2nd order differential equation
x(y"')^20 + y = 3x^398 -> 3rd order differential equation
y' + y^3 = 0 -> 1st order differential equation
(x^50)y" + (y')^300 + y = x -> 2nd order differential equation
x(y"')^20 + y = 3x^398 -> 3rd order differential equation
