To be more precise, 'I'd like to have ellipsoïde and à deux nappes, for instance. Thanks. Here is the interact. And here is the code: var('x,y,z') quadrics = {'Ellipsoide':x^2+y^2+z^2-1,'Paraboloide elliptique':x^2+y^2-z,'Paraboloide hyperbolique':x^2-y^2-z, 'Hyperboloide une nappe':x^2+y^2-z^2-1,'Hyperboloide deux nappes':x^2-y^2-z^2-1, 'Cone':x^2+y^2-z^2} @interact def quads(q = selector(quadrics.keys(), label='Quadrique'), a = input_box(default=1, label="$a$"), b = input_box(default=1, label="$b$"), c = input_box(default=1, label="$c$"), r = input_box(default=3, label="$r$")): f = quadrics[q].subs({x:x/a}, {y:y/b}, {z:z/c}) if a*b*c==0 or q=='Cone': pretty_print(latex(f)+'=0 '+'(dégénérée)') else: pretty_print(latex(f)+'=0') p = implicit_plot3d(f,(x,-r,r),(y,-r,r),(z,-r,r), plot_points = 75, mesh=1, opacity=.7) show(p)  2018-01-29 08:11:21 -0500 received badge ● Nice Question (source) 2018-01-28 16:20:47 -0500 asked a question plots of complex numbers Say I want to plot the 6 solutions of the following complex equation. What is the best practice? EDIT by @tmonteil: to lower dependency between Sage services in the long term, here is the code provided in the sagecell: var('z') solutions = solve (z^6==-8, z) for i in range(0,6): show(solutions[i])  2018-01-27 12:50:50 -0500 received badge ● Supporter (source) 2018-01-25 16:31:39 -0500 asked a question pretty_print in interact labels I have written the following interact. How cant I get the labels right? For instance, I'd rather have $N_0$ rather than N0. Can I achieve this with pretty_print? 2018-01-19 14:11:30 -0500 commented answer @interact : Fix the default rendering Thanks kcrisman! 2018-01-19 14:11:04 -0500 received badge ● Scholar (source) 2018-01-18 09:45:46 -0500 asked a question @interact : Fix the default rendering I have created the following interact. It plots the partial sums of a series up to N, et prints out the last one. The default rendering yields a DeprecationWarning and does not show the partial sum value. When you update the data, the rendering is fine. How can I fix this? 2015-11-06 19:14:25 -0500 received badge ● Famous Question (source) 2015-06-19 18:28:21 -0500 received badge ● Notable Question (source) 2015-06-19 18:28:21 -0500 received badge ● Popular Question (source) 2014-08-11 10:05:38 -0500 received badge ● Student (source) 2014-08-08 10:42:03 -0500 asked a question How to reset variables? I am using the Sage-6.2 app on an iMac (Mavericks). I have solved a couple of linear systems in my running worksheet for which the solution set requires a parameter. I am now at 'r7'. How do I reset this back to 'r1'? Also, is there something equivalent to Maple's 'restart'?
