I had this line close to the code above: [seq(Statistics:-Sample(e*cos(Pi*t), 1)[1], t = 1 .. 50)], that is I knew how it should be. Had Pi and pi looked differrently in typset output, i'd have readily identified the problem. I verified by paste&amp;copy&nbsp; from the output matrix entry, and it did give me the simplification I sought, which let me think of things other than looking back at the code.<br /> <br /> Your advisor resourse is great, thank you! </p> <br type="_moz" /> <p><img alt="" src="file:///C:/DOCUME~1/kostenko/LOCALS~1/Temp/moz-screenshot-1.jpg" />doh!
