    Problem 1:

    Find solution for:


    using power series methods.

    Answer 1:

    I get a recursion formula:


    and a final answer:


    Does that look right?

    Problem 2:

    Use Euler's method to solve:


    Answer 2:

    Using the quadratic equation to solve for r:



    Which means that:

    [tex]\lambda\,=\,\frac{1}{4}[/tex] AND [tex]\mu\,=\,\frac{\sqrt{7}}{4}[/tex]

    And finally:


    Thanks for the checking in advance!
