I need same packages that Ed asked for.
Nowadays I do geometry coding myself basic functions in SAGE worksheets (to
do intersection of lines etc).
I do this using the Rational Trigonometry philosophy :-)..see njwilderger
youtube videos and book.
Previously I played a little with Tex tools

Ok! Thank you! Do you have some idea about the first question?
*I want to add to A1 the square root of theta^3+3*theta+5.*
*The problem is that when I consider the following:*
gamma2=theta^3+3*theta+5
AA1.xbar=PolynomialRing(A1)
AA.gamma=A1.extension(xbar^2-gamma2)

Is this a correct method?
Should work too,

Steps 2 to 4 *used to be* equivalent to simply doing
We do have convex hull and lines. What would be lacking for your
application are discs and their intersection with polyhedra.
sage: line = Polyhedron(vertices=[(0,-1)], lines=[(1,1)])
sage: (triangle line).vertices()
(A vertex at (8/5, 3/5), A vertex at (3/2, 1/2))

which, to me, is a very useful answer. But other sums are simply wrong.
k = var('k')
sum(x^(2*k)/factorial(2*k),k,0,oo)
I'm working with Maxima 5.33.0. I get
simplify_sum ('sum(x^(2*k)/factorial(2*k),k,0,inf));
= sqrt(%pi)*bessel_i(-1/2,x)*sqrt(x)/sqrt(2)
which seems
I have defined two extensions A1 and A2 over a finite field Fp2 with
generator b,
A1.theta=Fp2.extension(Ep)
A2.z=Fp2.extension(Q)
being Ep and Q polynomials.
Now I want to define a homomorphism between those algebras. I have already
computed alpha, that is the element in A2 where theta is
Glad to see this has gained some traction. Here is an illustration of the
immediate issue for which this would have been helpful. I wanted to produce
an illustration explaining lines in the hyperbolic plane using the Poincare
disk model. It's the arc of a circle whose end points are on a given
Can you post a complete example? The following (simple) example works for
me (at least in 6.2.beta8):
sage: F=GF(5).extension(2)
sage: A1.y=F.extension(x^2+3)
sage: A2.z=F.extension(x^2+3)
sage: A1.hom([z],A2)
