Question

find the eigenvalues and eigenfunctions of y''-4y' +4y = - (lambda)y ; y(0)= y(pi)=0

Answer 1

Is this for university? @malcolm11235

Answer 2

it's a differential equations problem, so yeah.

Answer 3

Well eigenvalues/eigenfunctions are part of matrices/determinants/vector related stuff unit. I haven't done them yet but will soon. I can solve D.Es not dealing with eigenvalues and related stuff but have to do a lot more of it.

Answer 4

i take it you're in first year math courses?
