The eigenvalue condition forces omega to be an integer

Consider the boundary value problem (BVPdxdy/dx. Then which of the following statements are true?

  1. A.The BVP has a non-zero solution if
  2. B.The BVP has a non-zero solution if
  3. C.The BVP has a non-zero solution y = y(x) satisfying for every integer k if
  4. D.The BVP has a non-zero solution y = y(x) satisfying for every integer k if

You have the answer. Trap Analysis is why the other three were written.

Not a worked solution repeated four times — the specific reasoning error each wrong option was built to reward.
