| 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; During the study group presentation, it seemed that the PDE were broken down into the major groups listed below: Homogeneous PDEs - Constant Coefficients & Real Roots Homogeneous PDEs - Constant Coefficients & Complex Roots Homogeneous... |
| Thanks Again, your answer is exactly what I needed. |
| Thanks for the information, it was very helpful. When calculating eigenvectors using the functions Eigenvectors or Eigensystems they produce decimal values that are most times hard to understand and to visualize. There are other Eigenvectors... |
| Hi; To access a specific cell (specific row & column) in a Matrix you can use the `Part[]` function - for example `A[[1,1]]` gives the value of the cell in row 1, column 1 of Matrix A. Can the Matrix cell can be accessed by using a subscript and... |
| 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... |
| Thanks so much for your response, it was a great help. However, I do not understand where the vector function came from on the 1st line of your solution - {x + y, y - z, x^2 + 2 z}, and the Pi/10 as your last entry. Thanks again. It is... |
| Thanks so much for your assistance. Mitch Sandlin |
