mistake at plot?
what is the meaning of:
verbose 0 (4075: plot.py, generate_plot_points) WARNING: When plotting, failed to evaluate function at 121 points. verbose 0 (4075: plot.py, generate_plot_points) Last error message: ''
when I try to do:
sage: var ('z,t')
(z, t)
sage: z = function ('z',t)
sage: z = 1/2*sqrt(14644013671875*(3.55214000000000e12*sqrt(t) + 1.97774000000000e13*t^(1/4))^3/(14644013671875*(3.55214000000000e12*sqrt(t) + 1.97774000000000e13*t^(1/4))^3 - 135618210615234381652297748904336450246503209398960128) - sqrt(214447136422061920166015625*(3.55214000000000e12*sqrt(t) + 1.97774000000000e13*t^(1/4))^6 + 3864549077638520528470870886005025216199885162842192609280000000000*(3.55214000000000e12*sqrt(t) + 1.97774000000000e13*t^(1/4))^3 - 54181888058488411888503596938295863676921476134912455624013826749306153335312612762848157900410211283238912)/(14644013671875*(3.55214000000000e12*sqrt(t) + 1.97774000000000e13*t^(1/4))^3 - 135618210615234381652297748904336450246503209398960128) - 135618210615234381652297748904336450246503209398960128/(14644013671875*(3.55214000000000e12*sqrt(t) + 1.97774000000000e13*t^(1/4))^3 - 135618210615234381652297748904336450246503209398960128))
