Eigenvalue Problems,g a parameter (here l), we seek solutions that satisfy some special requirement (e.g., the series must converge for . = ±1). To obtain such solutions, we must choose particular values. for the parameter. In this case, . That is, polynomial solutions (which are required for convergence at. = ±1) aris

Variational Principles,ng the reflection and refraction of light at the boundary between two transparent media. What path does the light take in each case? For example, light is emitted from a source ., reflected from a boundary, and detected at a point .. Some possible paths along which the light might propagate to get f
