The given equation is. The given equation is solvable for x and it can be written as y 2x py. Thus the general solution is given by 2 y x 2 c e x y x 1 c 0 16 Obtain the general solution and singular solution of the equation y 2 px p2 y. The given equation can be written as xp 3 1 1 y 2 y px i s in theClairaut ' s form y px f p p p2 whose general solution is y cx f c 1 Thus general solution is y cx 2 c Differnetiating partially w. Dividing throughout by p2. Jan z Sol: Jan Derive one dimensional heat equation as c. July t x2 Sol: Consider a heat conducting homogeneous rod of length L placed along x-axis. Department of Mathematics.

The rod is sufficiently thin so that the temperature is same at all points of any cross sectional area of the rod Also assume that the rod is insulated laterally and therefore heat flows only in the x direction. Therefore q1 the quantity of heat flowing into the cross section at a distance x in unit time is u q1 kA per second x x Negative sign appears because heat flows in the direction of decreasing temperature as x increases u decreases q2 the quantity of heat flowing out of the cross section at a distance x x i.

The amount of heat crossing any section of the rod per second depends on the area A of the cross u section Let u x.. Department of Mathematics.. July Sol: Equation 3 is the one dimensional heat equation which is second order homogenous and parabolic type.. Since the string does not offer resistance to bending.

The motion takes place entirely in the X Y plane. We shall find the displacement y a function of the distance x and the time t. Since the is no motion in the horizontal direction. Consider the motion of an element PQ of length s. Gravitational forces on the string are neglected. We shall obtain the equation of motion of string under the following assumptions. The string is perfectly flexible and offers no resistance to bending Points on the string move only in the vertical direction.

Consider a tightly stretched elastic string of length l stretched between two points O and A and displaced slightly from its equilibrium position OA. Let m be the mass per unit length of the string. Jan 2 Solution: Here we first find z by integration and apply the given conditions to determine the arbitrary functions occurring as constants of integration.

Equation 3 is the one dimensional wave equation which is second order homogenous and parabolic type Mass of an element PQ is m s..
