Show that the following SL problem has a negative eigenvalue
y"(x) + Ay(x) = 0,
y'(0) = 0,
(y(1) – y'(1) = 0.
Transcribed Image Text:Show that the following SL problem has a negative eigenvalue y"(x) + Ay(x) = 0, y'(0) = 0, (y(1) – y'(1) = 0.
Hint: Only study the case A < 0, use the intermediate value theorem.
Note 1: The IVT state that if f is continuous and there are a, b such that f(a) and f(b) have
different signs, then there is c between a and b such that f(c) = 0.
Note 2: In order to find some suitable values for a, b, you may want to use Mathematica to
plot f.
