Please, can anyone tell me > the significance of the superscript bracket. It means the partial derivative of BesselI[nu,s] with respect to nu, evaluated at nu = 5/2. That is Derivative[1, 0][BesselI][5/2, s] If you enter D[f[x,y],x] /. x -> 5/2 or Derivative[1,0][f][5/2,y] you will get a similar expression. Note that Mathematica can numerically evaluate such expressions for numerical s. For example, enter Derivative[1, 0][BesselI][5/2, 0.1] See also http://functions.wolfram.com/03.02.20.0011.01.
