# Eigenvalue Problem : Transcendental Equation, Positive-Definite and Orthonormal

Solve the eigenvalue problem

as follows:

Let U = ... be a two-component vector whose first component is a twice differentiable function u(x), and whose second component is a real number u1 Consider the corresponding vector space H with inner product

Let S C H be the subspace

....

and let

....

The above eigenvalue problem can now be rewritten in standard form LU=)U with U E S.

(a) PROVE or DISPROVE that L is self adjoint, i.e. that (V, LU> = (LV, U).

(b) PROVE or DISPROVE that L is positive-definite, i.e. that (U, LU) > 0 for U does not equal 0.

(c) FIND the (transcendental) equation for the eigenvalues of L.

(d) Denoting these eigenvalues by )1, )2, )3, . . . , EXHIBIT the orthonormalized eigenvectors U, n = 1, 2, 3,. .., associated with these eigenvalues.
