comment Properties of commutative ring and ideal related problem
@SteveD I was wondering how you know this is the actual GRE question... (I tend to believe your observation though, since the OP asked a lot of at least GRE-type questions.)

comment Finding an algebra of smooth functions on a manifold with a given product.
@JasonDeVito Could you explain more about your second observation? I wonder how "maximal ideal" shows up in this context. Thank you!

comment What are the connections between spectral expansion and differential operator?
@muzzlator Thanks for the comments! Yes, I know the spectral expansion facilitates solving differential equation, but is it the only motivation? (Just kidding: I myself find it easier to differentiate $x$ than to first write its Fourier expansion and then differentiate the expansion...)

Can I ask how to evaluate the second integral in you post?
