Boundary and Initial Conditions

Generally partial Differential equations denote the change or behaviour of a function.The boundary of a Differential Equation is defined as the closed interval over which the function is defined.Initial Conditions are values of the function at starting or initial position in the interval.These initial conditions will change based on the type of the Differential Equations.If the PDE is of second order we need two initial conditions to solve for PDE.If the PDE is of Third order we need three initial conditions to solve for PDE.
