Frobenius Method of Series  Solution
LecturesAssignments More           

After a brief discussion of some selected properties, Forbenius method of series solution is explained with help of four examples of second order ordinary linear differential equations. The four examples correspond to four different cases that arise depending on the nature of roots of the indicial equation.

Series Solution Explained WIth Bessel's Equation as an Example  
Lectures              Assignments            More

The Frobenius method classifies the series solutions into four cases depending on the nature of roots of the indicial equation. The Bessel's equation for different parameter  values gives rise the four cases. One solution is easy to obtain as is the case for any ODE  solvable by the Frobenious method. The second second solution leads to introdcution  of  Bessel functions of second kind.
