Homework Statement
It is stated in "Mathematical methods of Physics" by J. Mathews, 2nd ed, p274, that the Bessel function of the second kind and of order zero, i.e. [itex]Y_0(x)[/itex] can be approximated by [itex]\frac{2}{\pi}\ln(x)[/itex]+constant as [itex]x \to 0[/itex], but no more details are given in the same text.
Homework Equations
Could you show me how that approximation comes about?
The Attempt at a Solution
Visually I see the resemblance between the functions, but I cannot derive the approximation myself.
