Define a Python function rather than a symbolic function. def g(x): return sum(frac(j*p/q), j, 0, x)

Sage refuses to evaluate summations... I'm trying to define a function g(x) = sum(frac(j*p/q), j, 0, x) where p, q ar

How to compute an ideal of specific norm? So I was wondering if there was a way to compute ideals of a certain norm some

I want to display the origin on the graph. I'm displaying the graph of a function as follows: d = 2 n = 1 psi(x) = sqr

Ideally, provide a minimal concrete example, with code to define the objects, that can be copied and pasted in a fresh S

Welcome to Ask Sage. Thank you for your question.

GP compiler problem When I do individual calculations the algorithm seems to be fine but when I do multiple iterations i

Solve cannot get algebraic answer without taking logarithm I'm trying to solve the simple, one variable equation: 8^(3*x

The reason is simple. A graph coloring is a dictionary whose keys are colours and values are lists of vertices of that

There is not really a difference. Both answers involve an arbitrary constant. Your C is the opposite of Sage's _C.

Going through the group of units This implementation suffers from the defect that elements of H have G as their paren

This is a long comment rather than an answer. It provides some code to define the objects in the question, in the hope

If we accept that exp(12*pi*i*i) is transformed into cosh(12*pi) - sinh(12*pi), then the observed behaviour is not a bug

Not sure what you mean by "compile". Maybe you can say more on how you are using Sage.

To only get those, change two things in the function: change M = MatrixSpace(QQ, d) to M = MatrixSpace(ZZ, d) change i

One way is to define a generator that goes through symmetric zero-one matrices and yields those that are invertible. Th

This has to do with how implicit_plot works. In order to decide where the desired expression is zero, it samples values

Well done. You can accept your own answer to mark the question as solved.

For certified error bounds use Arb via RealBallField and ComplexBallField.

Some functions in Sage or NumPy do not support symbolic arguments. Plotting using such functions requires using them as
