Classifying Singular Points: Regular or Irregular?

Click For Summary
SUMMARY

The discussion focuses on identifying singular points in the differential equation xy'' + (1-x)y' + xy = 0. The singular point identified is x=0, which is classified as a regular singular point. The method to find singular points involves setting the coefficient of y'' to zero and solving for x. Additionally, the discussion highlights the importance of understanding the definition of a regular singular point to fully grasp the classification process.

Homework Statement


Find all singular points of xy"+(1-x)y'+xy=0 and determine whether each one is regular or irregular.


Homework Equations


The answer is x=0, regular.


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.
