comment finite dimensional vector spaces of functions left invariant by translation
Assuming $f$ is differentiable, can we show every such subspace is spanned by $\{ e^{\lambda x} x^k \sin x, e^{\lambda x} x^k \cos x\}$ ?

I never claimed that those spaces spanned the entire space, this isn't the purpose.

comment Can you recommend a book to learn to teach math to a child?
The book is for the teacher, not the child. And yes, that particular book is appropriate for your purpose. Think instead of patttern matching.

Wonderful, I actually posted an link to an excerpt of this book, but I didn't know what the book was. I think I actually may have had Dimitri as a "colleur" in 2000.
