Ok. This is consistent with the Fresnels where we removed the "_" too. > Regardless of what we do, I think we should use the notation > that puts the derivative as one of the arguments rather than have a > separate airy_prime function. I vote against this for mainly two reasons: - All formula become more complicated to read and write and we make the Airy function essentially a 2-Argument function. - All other major CAS do provide separate functions which are also standard mathemtical notation. (Hence users may expect these functions. For example I overlooked the implementation of mpmath ;-)) Maybe there are even more reasons to do this, but these two come to my mind right now. You are right, for mathematical reasons we would not need extra functions. We even could write an unevaluated derivative. (Which in turn gives problems to express the second derivative which should simplify to Airys again.) For the same reasons we could express cos by sin or right away by exp. -- You received this message because you are subscribed to the Google Groups "sympy" group.
