Issues with the Maxima-plugin solving integrals from using mathematical input

#1

I use MacPorts "Maxima 5.45.1 using SBCL 2.1.11 on OS X 13.6/15.7. In mathematical input mode, running TeXmacs 2.1.1 and its Maxima-plugin, integrals are not properly evaluated:

Has anyone a clue how to fix this issue?

You should look into the plugin code and see why the translation is incorrect or not implemented. I guess you can find it in $TEXMACS_PATH/plugins/maxima/. Usually this is either implemented in scheme or in the plugin scripting language or in Python.

Hi try putting cdot before dx (and a space between d and the variable x)
int

In the same direction, note that “space” in math means really “function application” and that if you want multiplication then you need to type “space tab”.

Unfortunately @Yibbou, meticulously following your suggestion still produces an error message as \cdot is not correctly converted into “*” but “.” – for reasons beyond my understanding:

Anyway, thanks for your fast replies and help.
