    Chapter 1 - Series Solution of Differential Equations Price 0.11  |  0.11 Rewards Points

    We know that linear differential equations with constant coefficients can be solved and their solutions are elementary functions.* There also exists some methods in which linear differential equations (with some specific types of variable coefficients) can be solved and their solutions are elementary functions. In general, a linear differential equation with variable coefficients may not admit of any solution which is expressible in terms of elementary functions. In the present chapter, we shall learn the method of solving linear differential equations and obtaining solutions in the form of an infinite series.

    Chapter 6 - Partial Differential Equations Price 0.11  |  0.11 Rewards Points

    Partial differential equations arise in applied mathematics and mathematical physics when the functions involved depend on two or more independent variables. The use of partial differential equation is enormous as compared to that of ordinary differential equations. In the present chapter, we shall learn the method of solving various types of partial differential equations.

    In the last chapter, we studied the methods of forming partial differential equations. The next step is to solve partial differential equations. Solving a partial differential equation means to find a function which satisfies the given partial differential equation. A function satisfying a partial differential equation is called its solution (or integral). In the present chapter, we shall confine ourselves to the solution of partial differential equations of first order and at the same time linear in p and q.

A partial differential equation of first order need not be linear in p and q. In the present chapter, we shall study the methods of solving such equations. In the first part, we shall study the method of solving some special types of equations which can be solved easily by methods other than the general method. In the second part, we shall take up Charpit’s general method of solution.

    The Laplace transform* of a suitably defined function f of a real variable t is a related function F of a real variable s. The use of Laplace transforms provide a powerful method of solving differential and integral equations.

The ready tables of Laplace transforms has reduced the problem of solving differential equations to merely algebraic manipulation.
