+where [nu] is the /order/ of the equation, and may be an arbitrary
real or complex number, although integer orders are the most common occurrence.
This library supports either integer or real orders.
Since this is a second order differential equation, there must be two
-linearly independent solutions, the first of these is denoted J[sub v][space]
+linearly independent solutions, the first of these is denoted J[sub v]
and known as a Bessel function of the first kind:
[equation bessel2]
This function is implemented in this library as __cyl_bessel_j.
-The second solution is denoted either Y[sub v][space] or N[sub v][space]
+The second solution is denoted either Y[sub v] or N[sub v]
and is known as either a Bessel Function of the second kind, or as a
Neumann function:
The solutions are known as the modified Bessel functions of the first and
second kind (or occasionally as the hyperbolic Bessel functions of the first
-and second kind). They are denoted I[sub v][space] and K[sub v][space]
+and second kind). They are denoted I[sub v] and K[sub v]
respectively:

The two linearly independent solutions to this equation are called the
-spherical Bessel functions j[sub n][space] and y[sub n][space], and are related to the
-ordinary Bessel functions J[sub n][space] and Y[sub n][space] by:
