Differential Equation :-
The equation consist of derivative of the dependent variable with respect to independent variable or variables is called Differential equation.
For example :-
Order of Differential equation
The order of Differential equation is defined as the order of the highest order derivative exist in the given Differential equation.
For example,
The order of
Degree of Differential equation
The degree of Differential equation is defined as the degree of higher order derivative exist in the given Differential equation when all the other Differential coefficients are free from radicals.
Degree is defined when Differential equation is a polynomial in Differential coefficient otherwise degree is not defined.
For example
The degree of
Solution of differential equation
General Solution : -
The solution which contains arbitrary constants is called general solution. The number of arbitrary constants is always equals to order of Differential equation.
Particular solution :-
The solution which don't have any arbitrary constants is called Particular solution of differential equation.
