In problem [a] you may assume that there are no eigenvalues for λ ≤ 0. In problem [b] you will not be able to find the exact eigenvalues. You should find a condition on the eigenvalues of the form f(µ) = 0 where µ 2 = λ. In this case there is an eigenvalue λ < 0. Find as equation for this eigenvalue in the form g(µ) = 0 with −µ 2 = λ and estimate λ by graphing g(µ) and estimating where it is zero.
