Bessel functions of the first kind or second kind

Bessel functions of the first kind besselJ(n,x) or second kind besselY(n,x) for both positive (blue) and negative (red) real order n:

This allows one to see explicitly that the two functions are linearly dependent for integer order, either coinciding for even order or being mirror images for odd order. It also allows one to see the relative location of the zeros of the two functions.
