LyX ⇒ Maxima TeX Conversion not Working in Lyx . . .

[BuntuLyX]

Greetings!

I have a simple question for the community today; but it's been troubling me for a while.

Suppose we have a straightforward equation formatted for Maxima,

Code: Select all

integrate(4*sqrt(1-(x^2)),x,0,1);

Then, desiring syntax for direct insertion into a *.lyx document, we run

Code: Select all

tex ('integrate(4*sqrt(1-(x^2)),x,0,1));

yielding

Code: Select all

4\,\int_{0}^{1}{\sqrt{1-x^2}\;dx}

Then, into a normally-headered *.lyx document, we insert

Code: Select all

\begin_body

\begin_layout Standard
\begin_inset Formula 
\begin{eqnarray*}
4\,\int_{0}^{1}{\sqrt{1-x^2}\;dx}
\end{eqnarray*}

\end_inset


\end_layout

\end_body

which, when opened in LyX (using either Octave or Maxima to solve/edit), does not return an answer to the document.

What might this newbie be missing to allow an equation converted through Maxima (tex) to run directly in a *.lyx document?

Thanks a bunch

Bump?

Great question. The problem stems from juxtaposing 4 with the integral sign without a the times sign. Instead of:

4\,\int_{0}^{1}{\sqrt{1-x^2}\;dx}

Fix it by removing blank spaces in the formula (\, and \;) and including a dot after the four:

4\cdot\int_{0}^{1}\sqrt{1-x^2}dx

runs OK... The result is \pi
