Find all singular points?

  1. Jul 31, 2013 #1
    1. The problem statement, all variables and given/known data
    Find all singular points of xy"+(1-x)y'+xy=0 and determine whether each one is regular or irregular.


    2. Relevant equations
    The answer is x=0, regular.


    3. The attempt at a solution
    I know that x=0 since you set whatever is in front of y" to 0 and you solve for x, right?
    And I think you supposed to take the limit as x approaches to 0 but I don't know which function to take the limit of.

    Have you looked in your text to see the definition of a regular singular point? What is it?
