It seems that maxima is not correctly configured. Follow the link to the wiki in my signature, you find instructions there. They should be valid also for current versions of SMath Studio.

Firstly, you have not install maxima.
Download latest version from this link.
Then do what maxima extension settings explained by mkraska.

Second, you don't calculate integrals with numeric solvers.
For symbolic calculations better to use maple or maxima plugin.
Here is your problem solved.

That's something I didn't know his to do.
I did tried assume(n>0,e>0) but seems it doesn't work like that.

Thanks, I learned a new thing.

I can't express what you taught me in smath. How should I represent the highlighted part in the picture?

It is the line() function.
You can either type it, or select from toolbar.
