Q: Question on result of improper integral type 2

NasserV 14.2 gives this result ClearAll[x] Integrate[Sec[x],{x,0,5*Pi/4},PrincipalValue->True]//N However, the youtube video I was studying from gives -0.8813 and also Maple gives same. Question is: Why does Mathematica give this extra imaginary value? evalf(int(sec(x),x=0..5*Pi/4,CauchyPrincipalValu...

Q: Do Covariant and Contravariant Indices Play a Role in Tensor Networks?

Truth hunterI am new to tensor networks and I have a question: In differential geometry and theoretical physics, tensors have covariant (lower) and contravariant (upper) indices, which determine how they transform under coordinate changes. In tensor networks, tensors are used to represent quantum many-body s...

Q: Classify a multi-band raster image into discrete categories

MigwellI have a PNG of a map, which uses RGB colours. It has about 6 colours that it uses in the map, which are fully discrete. Here is a small snippet from the map: I want to generate something like a polygon for each region of that image with contiguous colours. I want a tool that will factor in all ...

Q: Non transient physical homogenous solutions?

dareenIn the context of RLC, LC, and RC circuits, which are typically modeled by second-order differential equations, the homogeneous solutions usually exhibit exponential decay, consistent with energy dissipation in the circuits. However, I came across a note in my learning materials suggesting that t...

Q: tikz: scaling nodes using scope versus scaling them using options. I.e., \node[scale=<>] versus \scoped[scale=<>]\node is different

JasperWhy does using scale on a node using the scope environment cause its coordinate to scale, but when I use scale on a node using its options, only the contents are scaled? In the following code, the first P-node's coordinate is scaled by a factor of 2 --- the expected result. However, the second P-...

Q: Last digit in number of derangements

polfosolThere is a table at the bottom of the wikipedia article on deranged permutations, where the number of derangements for $1,...,30$ is listed. I noticed that the last digit of $!n$ is zero only when the last digit of $n$ is $1$, and just tested my hypothesis: Select[Range[100], NumberOfDerangements...

Q: Using "should" for expected actions

brumHere, point 3 https://www.ldoceonline.com/dictionary/should it is written that we can use "should" to make statements about what is expected to happen. Could we also use "should" to make questions if something is expected? Should Australia win tomorrow? - meaning if it is expected; not if it wo...
