However, an issue arises when I use integration. + </p> + <p> + If I enter \(\displaystyle\int x\,\mathrm{d}\,x\) with "<code>\int <enter>x d<tab><tab>x</code>" (spaces here are actually typed in while the "<code><tab></code>"s and "<code><enter></code>"s are their respective keys), I get this idiosyncratic error: + </p> + <pre>incorrect syntax: 1 is not an infix operator +integrate( x 1, + ^</pre> + <p> + This seems to be a bug when TeXmacs is translating things into Maxima. Just replace the "<code><tab></code>" between the integrand and the "\(\mathrm{d}\)" with a multiplication operator entered by "<code>*</code>". For example, <code>\int <enter>x*d<tab><tab>x</code> yields the correct result of \(\displaystyle\frac{x^2}{2}\) rather than the nonsensical error. + </p> + <p> + For reference, the source code of a demonstration document is included below in Scheme and XML-like (?) formats. + </p> + <pre>(document (TeXmacs "2.1.1") (style (tuple "generic" "maxima")) (body (document (session "maxima" "default" (document (unfolded-io-math (document (with "color" "red" (concat "(" (with "math-font-family" "rm" "%i") "8) "))) (document (concat (big "int") " x <mathd> x")) (document "" "incorrect syntax: 1 is not an infix operator" "integrate( x 1," " ^")) (unfolded-io-math (document (with "color" "red" (concat "(" (with "math-font-family" "rm" "%i") "8) "))) (document (concat (big "int") "x*<mathd> x")) (document "" (concat " " (math (with "math-display" "true" (concat (text (with "font-family" "tt" "color" "red" (concat "(" (with "math-font-family" "rm" "%o8") ") "))) (frac (concat "x" (rsup "2")) "2"))))))))))) (initial (collection (associate "page-medium" "paper") (associate "preamble" "true") (associate "prog-scripts" "maxima"))))</pre> + <pre><TeXmacs|2.1.1> + +<style|<tuple|generic|maxima>> + +<\body> + <\session|maxima|default> + <\unfolded-io-math> + <with|color|red|(<with|math-font-family|rm|%i>8) > + <|unfolded-io-math> + <big|int> x \<mathd\> x + <|unfolded-io-math> + \; + + incorrect syntax: 1 is not an infix operator + + integrate( x 1, + + \ \ \ \ \ \ \ \ \ \ \ \ \ ^ + </unfolded-io-math> + + <\unfolded-io-math> + <with|color|red|(<with|math-font-family|rm|%i>8) > + <|unfolded-io-math> + <big|int>x*\<mathd\> x + <|unfolded-io-math> + \; + + \ <math|<with|math-display|true|<text|<with|font-family|tt|color|red|(<with|math-font-family|rm|%o8>) + >><frac|x<rsup|2>|2>>> + </unfolded-io-math> + </session> +</body> + +<\initial> + <\collection> + <associate|page-medium|paper> + <associate|preamble|false> + <associate|prog-scripts|maxima> + </collection> +</initial></pre> + <div id="footer"> + <hr /> + <p><a href="/">Runxi Yu's Website</a></p> + + </div> + </body> +</html> |
