7740.10.2 Frobenius method for boundary-value problems
a) Suggested transformation and differential equation in v[x]
Solve DE using suggested transformation (solution is polynomial) => confluent hypergeometric functions of the first kind
Limits - boundary behavior
Finite y[0] => C[1]=0
Limit at origin => regular singular point
d) Attempt to evaluate limit at infinity (note that decreases faster than any polynomial in x) [note the Bessel case for e = 0 and hypergeometric case for e = 2]
Empirical search for stable eigensolutions (that approach zero as x approaches infinity)
Negative e
Zero e
Positive e
Fixed negative C[2]
Fixed positive C[2]
Systematic search for eigensolutions
Construct the characteristic equation and solve for eigenvalues
