Any clue why bool(arcsin(x) == 2*arctan(x/(1+sqrt(1-x^2)))) returns false where the expressions are mathematically equivalent.
I found that arcsin(x) - 2*arctan(x/(1+sqrt(1-x^2))) is not exactly 0 for all x in [-1,1]. In sage, is there any way to compare expressions with some numerical precision? -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
