There has been a discussion on (http://forum.texmacs.cn/t/typographical-issues-with-the-maxima-plugin-returning-integral-expressions-in-mathematical-output/937/11) on the flawed mathematical output of integral expressions returned by the Maxima-plugin.

Firstly, the spacing before the d and the variable x that the Maxima-plugin generates by default is much too large (See attachment 1 -- image_01.png) As defined in lines 111 and 116 of texmacs-maxima.lisp the LaTeX instructions \; translate into 0.27em horizontal space. Modifying these lines to

(append l `("\\int {" ,@s1 "}{\\,\\mathd\\hspace{0.05em}" ,@var "}\\big.") r))

    (append l `("\\int_{" ,@low "}^{" ,@hi "}{" ,@s1 "\\,\\mathd\\hspace{0.05em}" ,@var "}\\big.") r)

produces visually more pleasing results, as can be seen in attachment 2 -- image_02.png.

However this does not really solve the problem, as secondly, the plugin inserts multiplication signs after sin(x) and after the d. (See attachment 3 -- image_03.png)  The one before d is okay, but the one after is not only unnecessary but it also prevents reusing this output.  If you try to copy and paste the lhs of the equation in image_03.png into a Maximima input line you get the results as shown in attachment 4 -- image_04.
