Hello,

I am new and my English is bad. I wood like to transform my
http://struktron.de/FSK/Feinstrukturkonstante.xmcd
to
http://struktron.de/FSK/Test-FSK.sm
My (18), integral with sqrt, I can't solve. What can I do? Is it impossible?

Thanks for solution or suggestion,
Lothar W.

I can't see an equation (18) in either of the files (xmcd opened with SMath). I don't know of problems with integral and sqrt, but there are definitely porblems with integrating over functions defined using if(), see attachment.

Hello,

thanks for quick answer.
My first problem is, that I can't open my .xmcd in SMath Studio. There is a mistake in German:
Die Datei oder Assembly "TextRegion, Version=1.9.4868.42191, Culture=neutral, PublicKeyToken=null" oder eine Abhängigkeit davon wurde nicht gefunden. Das System kann die angegebene Datei nicht finden.
My system is Windows Vista.
Did You open my http://struktron.de/FSK/Feinstrukturkonstante.xmcd with SMath and how?

My (18) is a definition for the function G(U,V,beta). In the integral I need, that U and V are numbers and beta a variable.

Regards,
Lothar W.

You probably have the Cephes math plugin installed, at least your error message is typical for the problems it causes. See this post and the messages around it for details.

You also might try the inofficial distribution. It is portable and stores it's settings and extensions separately from the SMath version installed via Windows installer. It also comes with an extensive, yet very incomplete bilingual german/english handbook (pages of which I attached to the previous post).

See the printout of the imported xmcd file in SMath in the attachment.

Hello,

thank You very much for the portable version. With it I can open my .xmcd. The well known problems with text I know from Your very good handbook.
In my Test-FSK.sm I have the problem in (18) also with Your distribution (int( , , , ) - die Funktion ist nicht bestimmt).

My wish is, to give people a free program for testing my hypotheses. How could I solve that?
Discussions we have on ALLTOPIC.

1. Import the file and rework manually
2. (Off topic here) Import to Mathcad Prime Express. You need the full version to do so.

Edit: The Test-FSK.sm has equations only up to (13)
Edit: Give a hint, how the function should look like. Is it possible to input it manually?

Now I have it up to up to (18) in my Test-FSK.

My question: can I take functions like in Mathcad, with variable limits of integrals?

Thanks and regards

Just rename the dummy integration variable. Integral limit and dummy variable should not have the same name (That's not a software limit but a math rule).

Edit: Hint added to handbook page.
