I wanted to place a line through two points represented as variables.
I can do it when explicitly giving coordinates. I wanted to do
something like this example:
pointA = point((1,1))
pointB = point((2,2,))
myline = line([pointA, pointB])
Though I am getting errors like: ValueError: need more

Yes that code works in a single cell for me. When I put it in an
interact and plot I get an error. Below is a simplified part of the
program I am working on. I am using the online notebook. I find when I
comment out the lines with myTangent the plot will display correctly,
so there is something

Hi,
Using cython, I want to make optimal use of static data. The reason is
that lookup is (often) much faster than recalulating. I now use:
cdef list nice_list_name=[3 , 3 , 3 , 3 , 3 , 3 , 4 , 4 , 4 , 4 , 4 ,
4 , 4 , 4 , 4 , 5 , 5 , 5 , et cetera]
But this didn't increase the speed.
Notice that William's pointA is just (1,1), whereas yours is
point((1,1)).The reason for the unusual error message is that
sage: line??
shows that if we get any error from trying to make a 2D line, it
assumes you want a 3D line.
Okay it works when I define a point with just the

Tnx!
int* did the tric. Maybe an idea to mention this in the Cython manual.
Look at the amazing difference in speed

25 loops, best of 3: 1.35 s per loop

Are there any examples of using functions and classes from other
worksheets in online notebook? Would it be a case of getting importing
the worksheet or calling a specific function with the full path on the

but didn't
Good! The patch has been merged in 4.4.4.alpha0, so from the next
release you'll be able to use this without the need to apply any
patches.

Hello - I'm the IT guy trying to get Sage up and running for our Math
department. I downloaded the VMWare virtual appliance and got it set
up on the network properly. Now I would like to make sure that the
passwords have been changed before deploying it. I figured I'd SSH
into it and run passwd

What if your c_is_square code merely does what is_square does:
cdef is_c_square(Integer x):
return mpz_perfect_square_p(x.value)
