1. Sage can't guess the appropriate range for the y-axis. You have to specify it. Otherwise it will just take a box that contains all/most values, which is way too large if there are poles. 2. you have to "add" plots together to have them display in the same figure 3. there is probably an option for it. Try "plot?" and take it from there. for 1+2, you can use: (plot(e^x,(x,-2,5))+plot(1/(x*(x-1)*(x-2)),(x,-2,5),color="red",detect_poles=True)).show(ymin=-7,ymax=10) -- You received this message because you are subscribed to the Google Groups "sage-support" group.
