in mp-tool.mp, change: vardef sinh primary x = save xx ; xx = exp x ; (xx-1/xx)/2 enddef ; vardef cosh primary x = save xx ; xx = exp x ; (xx+1/xx)/2 enddef ; ^^^ (you need to run "texexec --make metafun") Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

the following definition in mp-tool.mp vardef sinh primary x = save xx ; xx = exp xx ; (xx-1/xx)/2 enddef should be vardef sinh primary x = save xx ; xx = exp x ; (xx-1/xx)/2 enddef until Hans has fixed the problem you may use \startMPinclusions vardef sinh primary x = ((exp x) - ( exp (-x)))/2 enddef ; vardef cosh primary x = ((exp x) + ( exp (-x)))/2 enddef ; \stopMPinclusions or if you prefer Hans' math definitions \startMPinclusions vardef sinh primary x = save xx ; xx = exp x ; (xx-1/xx)/2 enddef ; vardef cosh primary x = save xx ; xx = exp x ; (xx+1/xx)/2 enddef ; \stopMPinclusions Jens
