Thanks for the suggestions. I have now installed icedtea6-plugin and sun-java6-plugin together with their dependencies etc. Running sage still gives no output and no error message. However, when I run in notebook mode I get a solid black square with a message saying 'jmol loading' with a

Jack and All, Try opening up a new worksheet and rename it. Then try a 3D plot from the new work sheet. I have had a problem with 3D plot after I rotate a plot in a worksheet and then save it. After that I can not get 3D plot to work in that worksheet, however, if I open a new work sheet it

I just tried http://jmol.sourceforge.net/demo/dots/ and it worked perfectly. After opening a new worksheet in the notebook mode I still get a black square. Two questions: 1) Is notebook mode the only way to make 3d plots? 2) Is it possible that I have a path problem with sage in /tools rather

[sage-support] problem evaluating an integral

I am trying to evaluate a definite integral using SAGE and am getting some errors. I have evaluated the same integrals using Mathematica without a problem. Here is the integral in question: integral(0.29832198400/((13.12333*X + 1)^2* (15.74667*X + 1)),(X,0.05,0.3)) I get

When I load a worksheet the results of previous evaluations of cells are displayed. Is there to stop this? Is there a file I could delete. In one worksheet I am having a problem with 3D plot (Jmol), which I can't reproduce in other worksheets. I was able to get 3D plot to work in other cells
