Try E.lift_x(Integer(1)). The Sage type Integer is more fully-functioned than the Python type int.

As far as I understand, Sage renders LaTeX in the notebook using an installation of MathJax, and MathJax by default does

I think I have to join everyone else in being confused about what you're asking. Are you asking about embedding tikz in

I would also point out that tikz and latex are designed for presentation and so are good at certain things. Sage is inst

The first part is easy: beta = 1/50 P = line([(-0.5, 0), (0.5, 0)]) for i in range(-5, 6): P += point((beta + i/11

You could use the simplify_trig method: sage: var('theta') theta sage: cos(2*theta).simplify_trig() 2*cos(x)^2 - 1 sage

I now see a problem. I interrupted the computation since it was taking so long, so I don't know if it ends in an error.

In the last paragraph, what do you mean by D and P? They can't have been the values returned by A.diagonalization(), sin

Maybe this is a silly question, but why do you think that this matrix is diagonalizable? All of its eigenvalues are 2, a

See https://github.com/sagemath/sage/issues/6389: I don't think this is supported, although it would be nice if it were.

Please provide details: what does "stopped working" mean? And how did you install SageMath?

In the Terminal you may have to specify the path to the sage executable. (a) Where did you install SageMath? (b) In the

If you had many examples of A, B, C, or if you had more information about the type of formula, then someone might be abl

Hence the very first question I asked: "How are you defining your polynomials in the first place?"

Why not just start with R.<x,dummy> = QQ[] and then any polynomials you later construct in x are automatically

Great, I'm glad!

One other question: what messages does ./configure print at the end? That would be useful to know.

To make sure that a polynomial f has the correct parent and therefore the desired methods, I don't see a more straightfo

How are you defining your polynomials in the first place? The dummy variable seems pretty straightforward to me: just se

You could also post the question to the Google group sage-support, along with the file SAGE_ROOT/config.log.

My only two further ideas are (1) restarting the computer, starting a new terminal session, and then once again trying m

You can run make distclean which should restore things to pristine status. (This has pretty much the same effect as dele

My guess is that you didn't do source SAGE_ROOT/.homebrew-build-env. This has to be done in the same Terminal session as

SAGE_ROOT is now ~/sage/sage-10.0/ or something along those lines: it's the directory where README.md is, for example. S

Did it fail? It may have unpacked the tar file and then run into errors (for reasons I don't understand) after that. One

Instructions for installing SAGE from source on MacOS are hard to follow. I am trying to follow the instructions at http

You will have to decide where to install Sage. Once you compile it, you cannot move it or else it won't work; if you dec

This question is confusing. Are you asking how to find B, given A and C and a formula for combining A and B to get C, or
