Can someone help with my differential equation involving power series?

Click For Summary
SUMMARY

The discussion centers on solving the differential equation y'' + x²y' + xy = 0 using power series methods. The user has derived two solutions, y1 and y2, which they believe match the textbook answers but seeks clarification on potential errors in their approach. The community emphasizes the importance of presenting algebraic work directly in the forum, preferably using LaTeX, to facilitate better understanding and feedback.

PREREQUISITES
  • Understanding of differential equations, specifically second-order linear equations.
  • Familiarity with power series and their convergence properties.
  • Proficiency in LaTeX for formatting mathematical expressions.
  • Basic knowledge of ordinary points in the context of differential equations.
NEXT STEPS
  • Study the method of Frobenius for solving differential equations at ordinary points.
  • Learn how to derive power series solutions for second-order linear differential equations.
  • Practice formatting mathematical content using LaTeX for clarity in online discussions.
  • Review examples of common mistakes in power series solutions to enhance problem-solving skills.
USEFUL FOR

Students studying differential equations, educators teaching mathematical methods, and anyone interested in mastering power series solutions in the context of ordinary differential equations.

It's possible no-one will have the patience to decipher your attachment. The ability to post images is really intended for photocopies of typed text and diagrams. For your own algebraic working you should type directly into the web page, preferably in Latex.
