Differential equation
are those equation which contain dependent ,independent variables,derivaives and partial derivatives
order:
the order of the differential equation is the order of the derivative
of the highest order occurring in the differential equation.
Degree:
The degree of a differential equation is the degree of the highest order differential coefficient appearing in it subject to the condition, that it can be expressed as a polynomial equation in derivatives.
General solution:
A solution in which the number of constants is equal to the order of
the equation is called the general solution of a differential
equation.
Particular Solution:
Particular solutions are derived from the general solution by assigning different values to the constants of a general solution.
