Differential equations using Series

Click For Summary
SUMMARY

The discussion centers on solving the differential equation represented by the expression t²y'' + ty' - y = 0, given that y1(t) = t is a known solution. The user initially sought help on mathbin but later identified the correct method for finding the general solution as Reduction of Order. The second solution derived is y2(t) = 1/t, confirming the approach's validity and effectiveness in solving this type of differential equation.

PREREQUISITES
  • Understanding of differential equations, specifically second-order linear equations.
  • Familiarity with the method of Reduction of Order.
  • Basic knowledge of series solutions in the context of differential equations.
  • Proficiency in mathematical notation and syntax used in platforms like mathbin.
NEXT STEPS
  • Study the method of Reduction of Order in detail, focusing on its application to second-order linear differential equations.
  • Explore series solutions for differential equations, particularly in cases where standard methods are not applicable.
  • Practice solving various second-order linear differential equations to reinforce understanding of the concepts.
  • Investigate the use of computational tools for solving differential equations, such as MATLAB or Mathematica.
USEFUL FOR

Students and educators in mathematics, particularly those focusing on differential equations, as well as anyone seeking to enhance their problem-solving skills in advanced calculus.

Homework Statement



Given that y1(t) = t is a solution of t2y'' + ty' - y= 0 find all solutions.



The Attempt at a Solution


I already put it into mathbin asking somewhere else for help and it doesn't look like i can copy paste that syntax to here.

Could someone tell me if that is correct so far?
If so can you tell me where to go from there?
If not could you tell me where I made a mistake?

thank you.

After many hours of getting no where, I realized that the correct method to solve this problem is Reduction of order.

The answer is y2(t) = 1/t.
