= Bessel function
{wiki=Bessel_function}
Bessel functions are a family of solutions to Bessel's differential equation, which arises in various problems in mathematical physics, particularly in wave propagation, heat conduction, and static potentials. The equation is typically expressed as: \\\[ x^2 y'' + x y' + (x^2 - n^2) y = 0 \\\] where \\( n \\) is a constant, and \\( y \\) is the function of \\( x \\).
