Dear KDE/KAlgebra Thank you for your maths software package.
It appears to me that the 3-D graphs have a left-handed system of axes. The convention throughout maths and science is to use right handed axes. The direction of your z-axis should be reversed. Yours, Dr John Coffey Knutsford, England -------------- next part -------------- An HTML attachment was scrubbed...
