I think that in many cases people do not know that those packages are deprecated. I think it would be good if the user would be informed about this, for example when loading the module.

As a side effect the authors would be "forced" to rewrite their tutorials since it doesn't look pretty when the program is complaining.

Thank you for the comment. I know about this issue but at the moment I don't know how to solve it. The problem is that such a series doesn't fit into the internal data structure which is used to represent trigonometric series. The "general" coefficient is expected to be a single equation which is used to derrive all the remaining sin(n*x) or cos(n*x) terms. This makes easy to Add two series. If there would be a possibility how to specify different values for this "general" coefficient dependent on the value of "k" (e.g. using IF statement), it would be very difficult to Add this series to another series which is not fully "compatible" (doesn't have the same conditions for the value of "general" coefficient).

Please, let me know If you have any suggestions how to deal with this problem.

Thank you. It seems to be sufficient solution. Equations like 3(x-1) can be detected by mint syntax checker.

I didn't describe my problem properly. You are right that ln has complex values outside (-1,1) but I am in interested just in real values.

But I found that using of assumptions together with some conversions solved my problem quite good. Thank you.

Hello, I tried before also x*x instead of x^2 but nothing has changed. As I said before, the problem was caused by wrong configuration of the system (some problem with priviledges). But I am not the administrator of that system so I can't tell more details.

Unfortunately, you can not use functions from the OrthogonalSeries package together with the FourierSeries package. These modules use different data structures. I did not implement the function similar to PolynomialMultiply. The FourierSeries package can manipulate just with trigonometric polynomials (OrthogonalSeries package manipulates with orthogonal polynomials). Please, could you more precisely specify which feature do you lack? Maybe I will be able to implement also this function. Thank you. Karel Srot

I found it. :-) Thank you.

Please, can you write a short example which shows how to overload an operator in Maple 6 (or later). Thank you. Karel Srot
