This should be
Dx = f.derivative(x)
In your example Dx is 1, and the graph is correct.

Ok, thank you very much. That's very helpful. Best regards.

y=|x|
1st derivative should be +1 x>0 and -1,X<0
f(x) = abs(x)
Dx = x.derivative()
p1 = plot (f(x),(-5,5),color='black')
p2 = plot (Dx, (0,5),color = 'red')
p3 = plot (Dx, (-5,0),color = 'blue')
show (p1+p2+p3)

Actually, I wonder if there is some list of the usual commands to use
on Elliptic Curves. I've been searching for it, but I only found the
commands to define an Elliptic Curve (just over Q or a finite field,
but not over a function field, say Q(t) for example) and operate with
some of points in i
Wow, I can't believe so few have reported this problem. Really I've
nothing new to add other than solidarity -- I got this same error when
I tried it two weeks ago.
One difference in my setup is that I installed Snow Leopard fresh into
a new partition instead of upgrading an existing Leopard.

Hi,
When writing 15/100 instead 0.15 it outputs:
[x == 0.302350301169,
x == (0.67362336338 + 0.678659962463*I),
x == (0.67362336338 - 0.678659962463*I)]
Although solve only accepts from t
Hi,
I am trying to solve the following equation:
sage: f(x)=((1-0.15)/(1-0.15+(0.15/(1-x*0.15)^22)))^3-x
sage: solve(f,x)
This gives me the following error, which doesn't make much sense to me.
