| 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 |
| Hi; In trying to get a better understanding of complex numbers in the Laplace Transform, I have formed the following understanding from the webinar. Please correct me if my understanding is incorrect. It seems that there is quite a bit of... |
| 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... |
| Thank you - I will study the notebook. |
