| 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... |
| Hi; In the code sample below, I am trying to open and display the contents of a notebook named "StereographicProjection" from within an open notebook with both notebooks being in the same directory. My thinking is that with the exact same code in... |
| Hi Ankit; In calculating both the amplitude and phase angle in electrical circuits, that contain capacitors and inductors, there is a technique called Phasors - which greatly simplifies the calculations. The phasor calculations are easily... |
| Hi; When I replace {x,y,z} with {u,v,w} in the equation below, the answer does not seem to be exactly correct. For example, shouldn't Sqrt[v^2] reduce to simply v and (w^4)^(1/4) reduce to w? Something that makes things ever more confusing is... |
| Hi; It is my understanding that Mathematica can perform calculus integration range coordinate transformation from, for example, from Cartesion to Polar or Cartesion to Cylindrical or Cartesion to Spherical or any other variation. However, I am... |
