Changes http://page.axiom-developer.org/zope/mathaction/177ExpandCos2X/diff -- expand (cos (x+y)) and expand (cos (x+y+z)) are right.
Is it possible to expand cos (2*x) = 2*cos(x)^2-1 or 1 - 2*sin(x)^2 -- forwarded from http://page.axiom-developer.org/zope/mathaction/[EMAIL PROTECTED] _______________________________________________ Axiom-developer mailing list Axiom-developer@nongnu.org http://lists.nongnu.org/mailman/listinfo/axiom-developer
