I am running Ubuntu Mate 20.04 on a raspberry pi 4, and have installed
Sagemath 9.0 using the Synaptic package manager. I can open a python3
notebook, but the sagemath 9.0 kernel refuses to start. Can someone make a
suggestion?
Here is a transcript of my last attempt.

derivative treats all parameters in the definition of a function as
constant. Suppose some of them are themselves unknown functions of the
variable.
I would like a procedure Derivative which accepts a list of these
parameters and returns an appropriate expression.
For example, if

Try checking the value at zero.

I admit I don't understand what is happening in the following snippit:
def f():
t=var('t')
t=5
a=2*t
return a
t=3;t;f();t
3
10
t
This was executed in a sagews cell
I think that the t which is referenced in f should be a local variable.
However the value of t outside of f is
var, but now I know when to use SR.var instead

I get this warning when I start a sage notebook--
*InsecureWarning: Not using mpz_powm_sec. You should rebuild using libgmp
>= 5 to avoid timing attack vulnerability.*Haven't used a sage notebook for
awhile, but seem to recall that I should ignore this warning. Is this
correct?
If not, how
thanks. i'll try it.

I would like to restrict a 3d plot to a certain box in space, say (x,0,1)
(y,0,1),(z,.5,1.5)
This would be useful in many situations, say when you want to inspect the
part of a graph of z=f(x,y)
where z is between a and b.
It doesn't appear that is possible. Is there an option I am missing?
Hi Nathann
Here is a Wikipedia article with what looks very much like the python code

That's weird. I can't get it to print. It's there, because it's in a
string that I write to a file. I was just checking to see that the string
looked right before I wrote it.
This behaviour occurs for me in the notebooks at sagenb.org and
