Hi: I'm trying to show my students a plot of a rational function whose graph is basically 1, so I plotted f(x) = (x^2+0.0001)/(x^2+0.0001000001) However, there is a problem: Note the difference between plot((x^2+0.0001)/(x^2+0.0001000001), (x,-10,10)) (which dips down near x=0) and plot((x^2+0.0001)/(x^2+0.0001000001), (x,-10,10), ymin = -0.1, ymax = 1.5) (which basically looks like a straight line). Same problem for lists:

sage: L = [(x/100, f(x/100)) for x in range(-100, 100)] sage: list_plot(L) # bug? sage: list_plot(L, ymin=-0.5, ymax=1.5) # good This is using 'SageMath version 10.3.rc1, Release Date: 2024-02-29' on an ubuntu machine. Can anyone tell what is going on here? I'm happy to attached jpgs of the plots I get, if desired. For comparison, it appears that Sympy plots this correctly. - David Joyner -- You received this message because you are subscribed to the Google Groups "sage-support" group.
