eigenfunctions. help!

I would be very grateful for any help on the following question:

Find any single eigenvalue-eigenfunction pair, with a real eigenvalue, for the
following operator:

\textit{L} = (\partial^2/\partialx) + (\partial/\partialx) + 2Id

subject to the initial boundary conditions u(0)=u(pi)=0

welcome to pf!

hi chappyform! welcome to pf! :wink:

show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 


Since the derivatives are only with respect to x, you don't really need the partial derivatives.
 


what is 2Id?

Thread 'Direction Fields and Isoclines'

I sketched the isoclines for $$ m=-1,0,1,2 $$. Since both $$ \frac{dy}{dx} $$ and $$ D_{y} \frac{dy}{dx} $$ are continuous on the square region R defined by $$ -4\leq x \leq 4, -4 \leq y \leq 4 $$ the existence and uniqueness theorem guarantees that if we pick a point in the interior that lies on an isocline there will be a unique differentiable function (solution) passing through that point. I understand that a solution exists but I unsure how to actually sketch it. For example, consider a...
