(wx)Maxima: determining the number of parts of an expression
I'd like to use part to handle expressions of different length but have not been able to find anything in the documentation that addresses how to determine the number of parts of an expression.
I do have an upper bound for the number of parts so, in…

Transforming Equations WxMaxima Ezunits
I'm having problems transforming equations, again...
Setting up the functions b(a) and c(b) works. Inserting them into each other also works to get from a temperature to a current c(b(a)). But now I want to flip it around a(c). The result should be…

Maxima texput for sqrt function
I was trying to redefine the output for sqrt() in Maxima, using texput, but am getting an error that I can't make sense of.
This is the function I wrote for creating the desired string:
sqrt_tex:lambda([e], printf(false,"\\csqrt{~a}",…

(wx)Maxima: literal order of polynomials
The documentation for powerdisp indicates that the options are either to display as a truncated power series, or from the greatest power to the least; is there any way to have it display the literal order provided (when unambiguous)?
e.g. if the…

wxMaxima: "*" wrong number of arguments
I used texput to redefine the tex1 output for *:
texput("*", "", infix);
but this causes an error when there are more than two terms:
tex1(a*b);
> ab
tex1(a*b*c);
> "*": wrong number of arguments.
Any idea why this is happening or how I…

wxMaxima: understanding ratcoef
Ran into the following behaviour from ratcoef that I don't understand, and was hoping someone could help clarify what's happening.
ratcoef(3*sqrt(x)+5/sqrt(x),x,1/2);
> 3
as epected. However,
ratcoef(x^(3/2)+3*sqrt(x)+5/sqrt(x),x,1/2);

wxMaxima: set formatting for rational powers
I was wondering if there is some way to use texput to tell Maxima how to format powers when they are rational expressions.
e.g. I would like
tex1(2^(2/5));
> 2^{2 / 5}
instead of the default 2^{ \frac{2}{5} }.
Can this be done?

Mathematica's ListLinePlot in wxMaxima
I have the following functions:
P[t_] := P[t] = P[t-1] +a*ED[t-1];
ED[t_] := ED[t] = DF[t] + DC[t];
DF[t_] := DF[t] = b (F - P[t]);
DC[t_] := DC[t] = c (P[t] - F);
And the following parameters:
a=1;
c=0.2;
b = 0.75;
F=100;
In Mathematica I use the…

Maxima: best practice for defining local variables in terms of other variables, within a block?
I thought the purpose of a block in Maxima was to protect global variables from being accidentally reassigned; however, I am not totally clear on the roles / rules for the different parts of a block.
For example, if one defines the…

ezunits not so ez -- ideal gas
I'm having lots of problems with ezunits, can't seem to get the units and their conversions right. One should calculate the volume of 2 tanks at 20°C which are filled with 6kg H_2 at 700bar relative pressure.
The total volume should be 0.103 m^3 and…

wxMaxima transform trigonometric expression
I got a equation in the following form
f(t) = 2*cos(t) + 3*sin(t)
and I want to reduce it to something like
f(t) = (9 + 4)^(1/2) * cos(t - atan(3/2))
None of the trigonometric simplify functions seems to work. Is there a way to do so?
