Hello.
I tried to integrate a function several times (4x). I was amazed, that it works, and that I can draw graphs of these functions.

However results are not right. The progress of a functions (the shape) is what I expect - therefore I did not notice the bug immediately - , but it is not the same.

Did I something wrong? (There is something strange with variable "x". It is used as if it was a public variable, however it si private variable of the integration ...)

Can I integrate integral?
If not, can I hope you will add it on a wishlist?

AFAIK you can't solve double integrals (look here) except using the Maxima plugin.

Thanks for answer; I will try to find something about Maxima.

Hello.
I solved my problem with multiple integration using MAPLE PLUGIN sufficiently.

However I am amazed with the function MaximaTakeover - The formulas appear much better without prefix maple( ... ).
Maple has nothing similar, I think...

And Maxima does not work in my SMath. What is wrong?
First use of maxime function asks me for a path to maxima.bat, but there i no dialog for to find the file...

Any maxima function gets an error. See images.

Thanks for answer

sometimes maxima does that, just put MaximaControl("cleanup" ) to the beginning of code.

Hello thank you.

This is not my case. I think I have to reload/reinstall Maxima.
What I am lookong for is a description how to do it correctly.

For example, there is no maxima.bat in my comp ... ...

Take a look here.

Have you installed Maxima on your system? The portable SMath Studio provided my Martin Kraska is "with Maxima", hence if you don't use this version you need to install the program by yourself. The "Interactive Smath Handbook" (Tools > Plugins > Interactive Books) contains the infos to setup the plugin.
