Well you are dealing with numerically exctreme values here.
Let's look at the factor of (x**2+y**2) inside the lambda:
sage:
(exp(I*2000*(1.60217662*10**(-19))/(299792458*6.6260700*10**(-34)))-(sqrt(
:
I*(1.60217662*10**(-19))/(4*6.62607004*10**(-34)*299792458*2000))-1.60
:
217662*1
Hi,
If you want useful help, give the complete log of a minimal session reproducing
the problem, from start to finish.

I would to the first or the second
n(10^(-8))
n(10**(-8))
the third I think it's not right but I am an expert

I don't know why it doesn't display inline
%matplotlib inline
var("y")
a=plot3d(lambda x,y:(exp(I*2000*(1.60217662*10**(-19))\
/(299792458*6.6260700*10**(-34)))-(sqrt(I*(1.60217662*10**(-19))\
I used circuitikz with sage and it's fine ?
Can you detailed what you mean with tikz ?
I can't use sagetex, so I will try pythontex

Hi!

Sage is based on Python, thus, 10**(-8) definitely works.
In addition, Sage uses a preparser to make the user interface still
a bit nicer than Python. Ther
Hi, how does one write 10^(-8) ?
Is it as the conventional way 10**(-8) or is it 10exp(-8) ?

Hi, I tried many re-edits, and found a few errors along the way, however,
there seems not to be any errors left, still nothing happens when issuing
the plot3d command:
plot3d(lambda x,y:(exp(I*2000*(1.60217662*10**(-19))/(299792458*6.6260700*
:
10**(-34)))-(sqrt(I*(1.60217662*10**(-19))/(4*
Changed to:
sage: plot3d(lambda

Hi, I was wondering if SAGE can be used to solve a PDE in the form:
u(x,y)''+u(x,y)' + const = 0
?
Thanks!

Hi:
I typed a single page of basic math randomly. While doing so, I used
sagetex for randomization mostly. However, I realized a few things:
1. sagetex does not interact well with many environments including TIKZ.
2. It does not really nicely plug-into other environments in general
