Mmathwonk replied to the thread I Can one find a matrix that's 'unique' to a collection of eigenvectors?.In post #28, what matters is that the vectors xj span. And that they are eigenvectors is irrelevant. Indeed the eigenvectors of a...

Mmathwonk replied to the thread I Can one find a matrix that's 'unique' to a collection of eigenvectors?.Sciencemaster:..."Is there anything else I'm missing here?" I would say you are missing the basic property of a linear transformation...

Mmathwonk replied to the thread I Can one find a matrix that's 'unique' to a collection of eigenvectors?.k is the field of scalars in the matrix, e.g. k could be the reals. I think your analysis as to canceling out makes sense, but to me it...

Mmathwonk replied to the thread I Confused by proof in Hocking and Young.I took a quick look at that book and wondered why you were interested in such a tedious approach to topology. Then I noticed some very...

Mmathwonk replied to the thread I Can one find a matrix that's 'unique' to a collection of eigenvectors?.Thanks to pasmith and fresh_42, I think I finally understand your question. To paraphrase: A linear transformation is entirely...

Mmathwonk replied to the thread My Grade 11 Math mark is eating me alive. What do I do?.Relax. You are not bad at math, rather you are clearly better than average, way better. But you seem to be blinded by something I...

Mmathwonk replied to the thread Geometry: Similar Shapes.I believe all 6 similarities are possible with the numbers as given. E.g. with the numbers as given, one can apparently have angles...
-
Mmathwonk replied to the thread Geometry: Similar Shapes.I admit I still find this confusing, but it seems to me that all 6 possible similarities can occur, still with only two final answers of...
-
Mmathwonk replied to the thread Geometry: Similar Shapes.yes, I believe that is what I said.
-
Mmathwonk replied to the thread Geometry: Similar Shapes.the triangles could be isosceles, and hence have self similarities. right? i.e. we seem to be making the unstated assumption that the...
-
Mmathwonk replied to the thread Geometry: Similar Shapes.What surprised me was that there seem to be more than 2 ways the triangles can be similar, but they yield only 2 results for the...
-
Mmathwonk replied to the thread Geometry: Similar Shapes.I am also a retired college math teacher (over 40 years teaching). So I am on the side of Mark44 in this matter. I do not disagree...

Mmathwonk reacted to martinbn's post in the thread B How does the Riemann Hypothesis/Riemann Zeta function even work? with
Like.
So is the pole. It implies that there are infinitely many primes.
