| 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... |
| Hi; In using the Area[] function in conjunction with the ParametricRegion[] function to define the region, I get error messages. I would like to check the answer that I calculated using Green's Theorem by using the Area[] function. However, even... |
| Hi; I am having problems using the function LineIntegrate[] along with ImplicitRegion[] to calculate a line integral - see attached notebook. I am absolutely convinced it is something that I am doing incorrectly, but after reading the... |
| Would someone please tell me what I am doing incorrectly and/or show me the Mathematica recommended method of obtaining the potential equation from the gradient - see attached notebook. It seems that in attempting to find the anti-derivative... |
