I have an issue while trying to create a 1x3 grid with some figures. All I have is a system of three axes (made from a `Graphics3D[]` object which contains the `Arrow[]` function), and a sphere of given radius (constructed via the `ContourPlot3D[]`...
I have a simple problem and it seems that I can't reach a proper solution for it. I need to find and also graphically represent the intersection curve between two surfaces: a sphere of radius R and a paraboloid. These two figures are represented...
# Energy surface - Mathematica I am working with a triaxial rigid rotor, which is a 3D object with no symmetry axis, so the moments of inertia about the principal axes are all different. It is well known from textbooks that the energy (rotational)...
I must do a graphical representation of a surface which is expressed in spherical coordinates. For this, I saw that Mathematica has a straightforward method with the `SphericalPlot3D` function. Having $x_1$, $x_2$ and $x_3$ in my code as the...
I do a lot of work that require data visualization, so I must perform multiple plots. I usually try to keep a consistent design, and for each plot I mostly have to copy and paste the styling into the `Plot[]` function. However, sometimes when I...
I am trying to solve a system of three equations with Mathematica's `NSolve`, for some functions which depend on six parameters, however, three of them are fixed so only the other three will be my solutions. The program seems to work, and I get the...
I am currently working on a topic involving nuclear theory (the study of deformed nuclei). So for the past two days, I've been trying to fit some data; I developed a theoretical model that aims at describing the energy spectrum of a nucleus. The...
Hi there, I am working on a notebook that tries to solve a system of three equations that depend on a parameter, and for each value of that parameter (in a custom interval) I want to write the solutions to an external file. I saw that one can...
I'm trying to compute various sums which contain some CB coefficients, where the sum runs over the indexes m1,m2,m corresponding to each of the three angular momenta j1,j2,j. The thing is that when I try to evaluate such a sum, Mathematica shows...
