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…

wxmaxima transforming functions
I'm having problems with the 4th part of the exercise, I cannot get it to work in maxima:
firstly transform s_y(t) to t=... that should be t=sqrt(2*s_y/a_y)
then insert that into s_x(t), to get a new s_x2(s_y) function, where you don't insert a time…

Is there a way to solve Ternary first-order equation with Maxima?
I want to know the Solving Syntax for Ternary first-order equation on maxima.
For example;
F_A + F_C + F_E - 15 = 0;
-F_A *0.4 + 15*0.2 m + F_E*0.4 = 0;
F_C = 0.3*F_A + 0.3*F_E;
wanna know How to get the solution F_A, F_C, F _E?

How to simplify matrix in terms of an equation
I have an matrix in Maxima, let´s say (for simplification of the problem):
A: matrix([2*(a^2+b^2+c^2)])
But I know that:
a^2+b^2+c^2 = 1
How do I simplify that matrix in Maxima in terms of that equation, in order to obtain A = [2]?

wxMaxima doesn't give a numerical answer - even when using float()
I tried setting up a simple function in wxMaxima - but find that the answer is symbolic. I've tried using float() in conjunction with the function that I've created, but float() doesn't fully convert the symbolic answer to a single number.
Is…
