You would also calculate the g functions with respect to each of the four eigenvalues, and pass those handles as well. WebEigenvalue Problems A real number 2 such that the BVP (5) has a non-trivial solution y (x) is called an eigenvalue of the BVP and the function y (x) is called an eigen-function associated to (or corresponding to) 2 n. It turns out that if y (x) is an eigenfunction, then so is any non-zero multiple Cy (x), so we usually just take the constant C= 1. opening invitation sample

"WebNov 16, 2024 · Note that we subscripted an $n$ on the eigenvalues and eigenfunctions to denote the fact that there is one for each of the given values of $n$. Also note that we dropped the ${c_2}$ on the eigenfunctions. For eigenfunctions we are only interested in the function itself and not the constant in front of it and so we generally drop that.
