Hello PF, maybe you can help with this one!(adsbygoogle = window.adsbygoogle || []).push({});

I need to show that the Laplace transform of J_{0}(at) is (s^2 + a^2)^-1/2.

My prof told me to start with the form:

x^{2}y'' + x y' + (x^{2}+ p^{2})y = 0, where p = 0 ITC.

What have I got so far?....

Doing the Laplace transform on both sides, where Y stands forL[y]:

x^{2}(s^{2}Y - sy(0) - y'(0)) + x(sY - y(0)) + x^{2}Y = 0,

...then 3 lines of algebra...

Y = y(0)* (1 + xs)/(xs^{2}+ s + x) + y'(0)* x/(xs^{2}+ s + x).

Do I convolve these two terms on the RHS now? Do I factor the denominator first? Or do I use some recurrence relns for Bessel functions, which is what y(x) is?

Your help would be much appreciated!!
