wxmaxima, why my function don't integrate well?
jk_hermite(n,v):=expand((-1)^n * exp(v^2)*diff(exp(-v^2),v,n));
jk_prob1(k):=block( [],
int1:integrate(abs(jk_hermite(k,x)*exp(-x^2/2))^2,x,minf,inf),
b:sqrt(1/int1),

Solve a system of equations parametrized as element of matrix
i have this problem, need to solve with conditions and cannot find yet how to describe in maxima (or maple)
This describe a finite state machine (n variable).
S is a matrix of equations.
S[i][j] = a * S[i][j-1] + b * S[i-1][j]
i-1<0 or j-1<0 ->…

What is the difference between makelist() and create_list() in MAXIMA?
I have seen that there are two similar functions to create lists in maxima: create_list() and makelist(). In both cases, the arguments can be
(, , , , < the step>) or
(,…

Plotting piecewise function with Fourier series in wxMaxima
I'd like to plot the following piecewise function with Fourier series in wxMaxima:
for given values of constants.
Here's my current input in wxMaxima:
a_1(t):=A_0+sum(A_n*cos(n*ω*(t-t_0))+B_n*sin(n*ω*(t-t_0)), n, 1,…

How to achieve a particular simplification level of an expression in wxMaxima?
I have the following input in wxMaxima:
BC:(sqrt((L^2)-((R^2)*sin(α)^2))+R*cos(α))*tg(α)$
AC:(sqrt((L^2)-((R^2)*sin(α)^2)))/cos(α)$
v_B:ω*R*(BC/AC)$
v_B;
I get the desired result but it's in a quite complicated form. I would like to simplify it to…

How to properly substitute a value to the variable used in formula in wxMaxima?
I calculated a velocity vector and its module from the equations of motion of a point in wxMaxima:
x:3*sin(4*t);
y:2*cos(4*t);
r:[x,y];
v:diff(r,t,1);
v_mod:sqrt(v.v);
Now I would like to calculate the velocity for t=5. How can I do this? When I…

How to plot a path from equations of motion of a point in wxMaxima?
I have the following equations of motion of a point:
x:3*sin(4*t);
y:2*cos(4*t);
I already created a vector:
r:[x,y];
and did some operations but I don't know how to plot the path (the result should be an ellipse).
I tried various commands and…

Can't correctly factorize a polinomial whose coefficients have decimals (non-integer), how can maxima do it?
how are you?.
I'm trying to create a function that calculates the z-transform of a transfer function using the residues method but for that, I need the factors of the characteristic equation and the powers of the factors, so, in order to do that I…

Maxima doesn't work in wxMaxima settings only command line on mac
I just installed Maxima. I am trying to use wxMaxima. It doesn't seem to work. You can see here if I do 2*10; it doesn't seem to output it. It only works on the command line. I tried uninstalling and installing and it seems to be working on the…

Why don't I get a float result?
c2: (x-0.5)^2+y^2=1;
solve(c2,y);
cs2: map(rhs, %);
at(cs2,[x=0.5]);
I expect to see [-1,1], but I get this instead
What should I do?
Incidentally, maxima cannot plot this equation for a reason unknown to me.
plot2d(cs2, [x,-2.5,2.5],[same_xy,…

Automatically assigning name to a list created by iteration
I am currently trying to create a command for maxima that allows for iteration of a function and places the result in a list. I managed to create the iteration through a loop, and it successfully places the results in a list.
However, I would like…
