Maxima is an opensource Computer Algebra System based on the legendary Macsyma.

Maxima can manipulate a wide range of symbolic and numerical expressions. The system handles differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors.

Maxima yields high precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers. Maxima can plot functions and data in two and three dimensions.

Maxima crashes on relatively simple integral

I'm trying to Maxima-fy my Mathematica box options formula (https://github.com/barrycarter/bcapps/blob/master/box-option-value.m) but Maxima crashes on a fairly simple integration: load(distrib); pdflp(x, p0, v, p1, p2, t1, t2) :=…

Euler Project 401 at Maxima

Statement of the problem: The divisors of 6 are 1,2,3 and 6. The sum of the squares of these numbers is: 1 + 4 + 9 + 9 + 36 = 50 Allow sigma2(n) to represent the sum of the squares of the n-dividers. Thus, sigma2(6) = 50. And addition_sigma2 (n) is…

How can I evaluate an integration to a number?

I have some functions set up like this: f(x):=1-2**-x$ g(y):=integrate(f(x), x, 0, y)$ and evaluated them: f(1)$float(%); g(1)$float(%); but for g(1), I got a symbolic answer instead of a numerical answer. Using float() was an attempt to get a…

Is there a null value in maxima?

I have the following two functions: find(list, closure) := block( filter: sublist(list, closure), if length(filter) > 0 then filter[1] else null)$ find_index(list, closure) := block( filter: sublist_indices(list, closure), if length(filter)…

Order of variables in maxima x^2+y^2 becomes y^2+x^2

If I have the polynomial x^2+y^2 in maxima, then maxima will display it like y^2+x^2. Is there a way to specify that the variable x will be displayed before the variable y instead?

In Maxima, how to check whether a series converges?

I would like to create a function that returns true precisely if a series diverges to infinity. Unfortunately it seems that Maxima throws an error if a series diverges. I loaded the package simplify_sum and I hoped that…

Simplify same power multipliers

In Maxima, I can use "rootscontract" to combine multipliers with the same rational power: (%i1) x^(1/2) * y^(1/2), rootscontract; (%o1) sqrt(x*y) Is there a standard method to combine multipliers for arbitrary powers?: (%i2) 2^x * 3^x,…

Evaluating if two basis sets span the same subspace in maxima

Is there some function in maxima for evaluating if two bases span the same subspace. For example, I ask my student to calculate a basis of the null space of a given matrix. In my solution, I have a specific basis. But I want to make sure that if the…
