Laplace transform and bessels equation

Click For Summary
SUMMARY

The discussion focuses on finding the Laplace transform of the expression tJ''0(t), derived from Bessel's equation. The user employs Maple 14 to compute the second derivative of the Bessel function J0(t), represented as t*diff(BesselJ(0,t),t$2). The resulting Laplace transform is calculated as L = [1 + 2s^2 + s^4 - (s^2 + 2s)*sqrt(1 + s^2)] / (1+s^2)^2. Maple utilizes the differential equation for J0 and recursion relations to express J0'' in terms of J0 and J1 before performing the integration.

Homework Statement


I'm trying to find the Laplace transform of tJ''0(t), it's from bessels equation, but that doesn't matter too much at the moment, I just need to integrate (e^-st)*t*J''0(t) but am unsure how to go about this with the J''0(t) in there.

Maple 14 gets an answer:
t*diff(BesselJ(0,t),t$2): <---second derivative of J0(t), times t

f:=expand(%);
f := -t BesselJ(0, t) + BesselJ(1, t)

L:=int(f*exp(-s*t),t=0..infinity);

L:= [1 + 2s^2 + s^4 - (s^2 + 2s)*sqrt(1 + s^2)]/ (1+s^2)^2

Note: Maple used the DE for J0 and recursions to express J0'' in terms of J0 and J1, then it integrated that.
