How to force wxMaxima to calculate subfunctions?
I have the following code:
B1(a,b,c,d) := (1-c) + (1-b) $
B2(a,b,c,d) := -(1-c) * (1-b) $
B3(a,b,c,d) := c*d + b*a $
B4(a,b,c,d) := -c*d*(1-b) - b*a*(2-c) $
B5(a,b,c,d) := b*a*(1-c) $
_estP(x1,x2,x3,x4,x5) := x1*PTL1 + x2*PTL2 + x3*DTL1 + x4*DTL2 +…

Why is maxima showing only [ ] as output answer?
I'm new at using maxima, so when I wanted to solve these simultaneous equations $$y_1=-\left(\frac{2ax+c+ey}{2by+d+ex}\right)x_1+\left[y+\left(\frac{2ax+c+ey}{2by+d+ex}\right)x\right]$$
and, $$ax^2+by^2+cx+dy+exy+f=0$$
where the variables are $x,y$,…

Phase portraits with Maxima
Good morning all,
Just a very quick question:
I am using maxima to try and plot a phase portrait of a System of Differential Equations but im not getting the expected results.
u: (x^2-4)(y+2);
v: (x-1)(y^2-9);
sol: solve([u,v],[x,y]);

Maxima CAS Simplifying
Could someone please point me in the right direction as to how to enter this equation into Maxima CAS so I can simplify it?
(8a^2 + b^5 + c^-2) / (2a^5 + b^2 + c^-1/2)^-1/6
Many thanks

Generate a mathematical sequence of real numbers in Maxima
I need to perform a function that calculates the $n$th term of the next succession:
$1, 6, 16, 37, 63, 113, 163, 248, 339, 469, 591, 801, 971, 1221$...
For more information about the succession, I leave you this link.
I have tried to do it with the…

Plotting a set in wxMaxima
I have to plot the graph of this set in wxMaxima, but no manual has helped me. I've only been able to plot functions.
$$ {(x,y)\in\mathbb{R}\times\mathbb{R}: x\in[0,2]\wedge y\in[0,4]} $$
I tried this, which obviously did not work out

Lagrange Interpolation With Expand Returning a Wrong Result in Maxima
Recently I've been experimenting with polynomial interpolation to create a simple model of a battery discharge curve. My mathematics knowledge is a bit limited and this is part of my quest to find interesting things that my professors never…

Finding the area under the first three curves
I am asked to calulate the area under the first three curves of the function $$\frac{1 + \sin(2 x \pi)}{1+x}$$ on the interval $[0, 10]$.
I know how to integrate, but I don't know how to find the area under a specific section (like here, three…

Interpretation maxima %rnum_list
I don't really understand how to interpret the output of the function solve() in Maxima.
For instance, I have to sove this:
solve(a1*x1/(a1*x1+a2*x2)-r1*x1/(r1*x1+r2*x2),[x1,x2]);
[[x1=%r1,x2=0],[x1=0,x2=%r2]]
Are %r1 and %r2 2 constants ?
Thank…

simplification in maxima : removing terms with "small" contributions from an expression
Often in applied situations there are simplifications for small x.
For example $x<<1$ and $x/(1+x) \approx x$ or $(x + x^2)/c \approx x/c$.
Is there a way in Maxima to carry out these sorts of expression simplifications? If there's no way to do…
