| Hi; I am trying to plot a progression of time periods for a Predator - Prey model using the function ParametricPlot with constants, Eigenvalues (raised to k powers and Eigenvectors - see attached notebook. However, I am having trouble getting any... |
| Hi; I am trying to use the function Solve[] and Eigenvalues[] to solve for an unknown p variable as follows: SolveValues[Eigenvalues[{{6/10, 1/2}, {-p, 6/5}}] == {1,}, p] The problem is that the function Eigenvalues[] returns 2 values... |
| My end goal is to visualize how the vector plot changes in real time by manipulating one of the input variables. I can change the -7 input value manually and press Enter to get a different vector plot. However, I cannot seem to get the same results... |
| Hi; Please see attached notebook. Is there a better way to add text to Primitives such as Arrows in Graphics functions? I tried using the function PlotLegends which did not work ether. The following code does not generate the Blue Arrow Text -... |
| In order to get a better understanding of Eigenvectors and Eigenvalues, I am plotting both the given and calculated the vectors geometrically using Graphics[] and running into problems - see attached notebook. 1. The calculated eigenvectors... |
| Hi I am having trouble looking up the closing price of a mutual fund (for example "WHIAX") - see attached. I have tried several different methods all without success and would certainly appreciate any help. Thanks, Mitch Sandlin &[Wolfram... |
| Hi Mathematica Expert; In order to get a better understanding of 3 sets of data, I created a Venn diagram. Now, I would like to convert the Venn diagram into a statement that describes the sets of data, which I am having trouble - see attached... |
| Hi; I am trying to use the divergence theorem to calculate the outward flux through a centered sphere of radius "a". If I manually perform the calculation or use the SurfaceIntegrate function, I seem to get the correct answer. However, I cannot... |
| Hi; I am trying to create a VectorPlot3D of a vector field that is not actually given. However, I am given a parametric representation of the path, which I should be able to use to create the vector - see attached notebook. In any event, I am... |
| Hi; I am trying to understand Surface Integrals and how to calculate them using Mathematica's NSurfaceIntegral[], NIntegrate[] and other functions - See Attached Notebook. Honestly, I find the whole process somewhat confusing and need someone to... |
