Chapter 4: Q7E (page 199)

In Problems 5 through 8, determine whether Theorem 5 applies. If it does, then discuss what conclusions can be drawn. If it does not, explain why.
$y'' + ty' - t^{2} y = 0; y (0) = 1, y (1) = 0$

Short Answer

Expert verified

The differential equation has no unique solution.

Step by step solution

Find the value of p(t),q(t),g(t)

The given differential equation is $y'' + ty' - t^{2} y = 0$ .

So, $p (t) = t, q (t) = - t^{2}, g (t) = 0$

Check the result

From theorem (5) If p(t), q(t), and g(t) are continuous on an interval (a,b) that contains the point t, then for any choice of the initial values $Y_{o} and Y_{1}$ , there exists a unique solution y(1) on the same interval (a, b) to the initial value problems.

Here p(t),q(t),g(t) is a continuous function in the interval $- \infty < t < \infty$ ,but initial conditions are $y (0) = 1, y (1) = 0$ .So it is not an initial value problem.

Therefore, the differential equation has no unique solution.

This is the required result.
