| 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 Michael; Thanks so much, your modification worked great. However, I do not understand why Circle[] did not work and Disk[] did. Can you tell me why Disk[] worked and Circle[] didn't? Also, I noted that in your modification, you defined the... |
| 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... |
| Hi; I am having difficulty using the Disk[] primitive to define my integration region - see attached. This method is quite new to me, however it seems really elegant, and I would sure like to learn how to use it correctly. Thanks, Mitch... |
| Hi; I am trying to find the radius of the smallest sphere centered at {2,2,2} that also intersects the surface z = x + 1 using Lagrange Multipliers - see attached notebook. Believing that I have found the correct solution using Lagrange... |
| Hi Gianluca; Thanks for the quick reply, I really appreciate it. Actually, I was in the process of trying to verify the given answer when I ran into problems with the Solve[] function. What you stated is exactly right - that the given answer is... |
| The quizzes used to indicate which ones were incorrect, but within the last year that was changed. I found the old method of indicating which answers were correct educational and the new method not so much. Thanks, Mitch Sandlin |
| Hi Arben; In this response, I have attached a notebook outlining exactly what I hope to accomplish with this problem, which is understanding how to perform these calculations using Mathematica. The attached notebook shows 5 or 6 different methods... |
