Your function is comlex-valued on the interval (1,2) so the interval should be excluded sage: plot(sqrt((x - 2)*(x - 1)), (-4, 5),exclude=[1..2],plot_points=1000) + plot(-sqrt((x - 2)*(x - 1)), (-4, 5),exclude=[1..2],plot_points=3000) (other option - construct the graph from 4 pieces) -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
