Express solution as bessel function

  1. Jul 18, 2008 #1
    Hi Guys, i'm an undergrad student...and i have a difficulty trying to solve

    4xy" + 4y' + y = 0, and express the solution in term of Bessel function.

    I have tried Frobenius method...then....it didn't work..and i'm really confused

    Could anyone please help me with this?...i'd would really appreciate!

    Bessel fuinctions are defined as solutions to Bessel's equation.

    What is Bessel's equation?

    Can you, perhaps by changing varables, change your equation to Bessel's equation?

    Even if I multiply x thru, then divide 4 thru...i still don't get (x^2)y...hmmm..(i.e. Bessel eqn order of zero)..
