| 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. |
| Hi; When taking a partial derivative of: D[x e^y, y] I end up with an additional Log[] term: e^y x Log[e] Where is the Log[E] coming from? When performing these calculations manually, I would end up with e^y x without the... |
| Thanks, your response helped. As an aside, I am not sure where the word differential came from, and you are correct in that my request really has nothing to do with differential equations. Thanks Again, Mitch Sandlin |
| Hi Michael; Thanks so much for the information you provided. I find it useful to get my hands a little dirty and work with the mathematics, which I did with the information you provided - see attached notebook. In the notebook, I have questions... |
