I believe what you are looking for is “implicit_plot”

Hello,
Is there a way to plot non-parametric curve of 2-variables f(x,y)=0?
I've seen the documentation always employs rational parametrization or
uses plot3d.
best,
evrim.

Dustin, I don’t think you can use LaTeX syntax to define f.

Hi,
I'm trying to differentiate a pretty nasty function. However, I keep
running into invalid syntax problems.
a, c, g, k, t, g1, e2, t = var('a,c,g,k,t,g1,e2,t')
f=\frac{(\frac{g
Actually, I did -j8.

That sounds about right, Dmitry. It takes my server a few hours, and it is
an 8-core, 3.5 GHz processor.

Hello~
I am attempting to write a script in which I would like sage to solve
some symbolic inequalities *explicitly* for certain variables, but it
does not produce the expected results.
sage: var("x, y, z")
sage: solve(z>x/y, x)
This returns:
[[0 < y, y*z - x > 0], [y < 0, -y*z + x > 0]]

Could anyone tell me what I am doing wrong here?
sage: g(x,y) = ((x-y)/sqrt(1-(x-y)^2)/y)
sage: forget()
sage: var("alpha")
sage: assume(alpha>0)
sage: assume(alpha<1)
sage: assume(x>-1+alpha)
sage: *assume(x-alpha-1<0)*
sage: g(x,y).integral(y, alpha, x+1, algorithm="maxima")
And yet I stil
Don’t feel too bad, it took me a while to discover that method. :)

Is there a way to simplify sqrt(some_unit_of_measurement^2) without
knowing what's in the expression? Often a chain of computations will
lead to a result like the following:

First question: Is SAGE notebook susceptible to the Heartbleed bug when
run with secure=True?
Secondly, if so, would any connection that attempts to exploit that bug
necessarily show up in the console?

Have you looked into numpy module? It is not specific to Sage, but it
should work. Also, the indexing is a little bit friendlier.
sage: import numpy
sage: C = numpy.array(1, 2], [3, 4]], [[3, 4], [5, 6]]], [[[7, 8], [9,
10]], [[-1, -2], [-3, -4)
sage: C
array( 1, 2],
[ 3, 4]
