Advanced Linear Algebra Lecture 6.5: Self-adjoint differential operators

[@shuewingtam6210]

How can you derive Eigenvalue and Eigenfunction from the differential equation?would you let me know the video lecture to study them?

Power series / generalized power series (Frobenius)., Lecture 2.5-2.6 in Advanced Engineering Mathematics (www.math.clemson.edu/~macaule/math4340-online.html), or 3.8-3.9 of Differential Equations (www.math.clemson.edu/~macaule/math2080-online.html). Lots of overlap between these two pairs of lectures. Hope this helps!
