Unable to solve equations involving trigonometric funcions

I am trying to solve an equation involving trigonometric functions with Maxima, but I am not able to get the solutions. For example, solve(sin(x) = cos(x),x) returns [sin(x) = cos(x)] instead of %pi/4, and even equations with only one solution fail,…

wxMaxima: subindexed variables in functions work when written as "x_1" but not when written as "x[1]"

I'm having trouble defining a function in terms of variables with subindices. Using the makelist command I can create an unspecified function that depends upon the subindexed variables x[1] and x[2]. However, when I try to give an expression to that…

"Heap exhausted, game over" message in wxMaxima - Does ccl will work for me?

everyone, I'm trying to do some calculations and plot the results, but it seems that these are too heavy for Maxima. When I try to calculate N1 and N2 the program crashes when parameter j is too high or when I try to plot them, the program displays…

Obtaining real and positive solution of a polynomial equation in wxMaxima

I'd like to solve the following equation in wxMaxima: k*A*((T_2-T_1)/L)=ε*σ*A*(T_1^4-T_a^4) for T_1. The problem is that with regular Solve and Solve_to_poly I get extremely long outputs but not what I would expect. I need a real and positive…

(wx)Maxima: general roots of numbers, beyond sqrt?

I'm wondering if there are generalizations of the sqrt function in Maxima? In particular, I'd like to be able to control whether x^(a/b) displays as $x^{\frac{a}{b}}$ or $\sqrt[b]{x^{a}}$. I searched the index of the documentation for root but…

wxMaxima: how to define the inverse of a function?

I know that we can find the inverse of a function using solve e.g. f(x):= a*x+b$ [invf]:solve(f=f(x),x); However, I haven't been able to work out how to use this in the definition of a new function. I tried a few things,…

Using gradef with complex quantities in Maxima

I'm using gradef to declare the gradients of certain complex variables (that depend on an independent variable, say, t) in terms of other complex variables dependent on the same independent variable. But I'm running into some issues while applying…

How to get only the real solutions in Maxima?

I am trying to solve an equation with Maxima so that I only get real solutions if they exist; if there are no real solutions, or if there are not even complex solutions, I would like Maxima to return an empty list. For example, I would like that…

Reverse abscissa/ordinate axis in wxdraw2d or wxplot2d wxmaxima

By default, the draw/plot function plots y-axis values in ascending order (from bottom to top). In other words, -ve values are at the bottom of the graph and +ve values above the origin (towards the top of the plot). Can we reverse (see the figure…

Maxima: Is there any way to make functions defined within the main function be local, in a similar way to local variables?

I wonder if there is any way to make functions defined within the main function be local, in a similar way to local variables. For example, in this function that calculates the gradient of a scalar function, grad(var,f) := block([aux], aux :…
