anyone can help me?

I can't find the laplace because there are no initial boundary values

Homework Statement Bessel's equation of order zero can be written xy''+y'+xy=0 Homework Equations Denote the solution which is finite a the origin by J[SIZE="1"]0 Show that the Laplace transform of J[SIZE="1"]0 is proportional to (s^2+1)^-1/2 The Attempt at a Solution

Yah, I got it I really thank you for you clarification

should not |x| for any negative value equal to +x ? sorry but I am a little bit confused,

To be honest, I just assumed the exp(-|x|) is equal to exp(-x) for x between the minus and positive infinity and did the normal integration. Am I in the right track?

Homework Statement I have been trying to solve the Fourier transform of exp(-|x|) Homework Equations Do I need to split the function into two parts with different limits,i.e. the first has a limit from -infinity to zero and the secod from zero to +infinity. Please advise? The...
