;Request:
: Hi, I was wondering if someone can kindly please vectorize the flag of "Reichsbanner Schwarz-Rot-Gold"? I have included here two versions of the organization's logo to use as a base so the request can be done more quickly. Both version of the logo might need fixing though so please also do that if you vectorize the flag. One part that might be difficult is the [[Fraktur]] font for the words on the black and gold stripes. The words in yellow on the black stripe read "Reichsbanner Schwarz-Rot-Gold" and the words in black on the yellow stripe read "Einigkeit und Recht und Freiheit" (meaning "Unity and Justice and Freedom" which is the national motto of Germany and is taken from the [[Deutschlandlied|German national anthem]]).

It shows certain algebras and their supporting groups on basis elements. There are two lattices showing [[subalgebra]]s and [[subgroup]]s that correspond. It is requested that the illustration be put in a form appropriate for Commons as several articles might use it.

::No, the lattice indicates subalgebra by a descending line, vertical or slanted. Note for example that Complex is a subalgebra of Split-quaternion as indicated by a diagonal line. The top two algebras, Split-biquaternion and Biquaternion are independent, not connected. Similarly, the bottom two, Complex and Split-complex are not connected. Thus the display given is essential. — [[User:Rgdboer|Rgdboer]] ([[User talk:Rgdboer|talk]]) 20:22, 1 June 2025 (UTC)

::{{ping|cmglee}} This Commons image is excellent. As for the questions: Italics are not used for names of algebras and groups. Also, [[Split-biquaternion]] uses lower case b. Thank you for this very useful illustration of inclusions of algebras and their basis groups. The order notations (a,b) that are included correspond to data in [[List of small groups]], but since the labels of groups are standard, the extra notation may confuse a novice. — [[User:Rgdboer|Rgdboer]] ([[User talk:Rgdboer|talk]]) 21:19, 3 June 2025 (UTC)

:::Thanks, {{ping|Rgdboer}} I've updated the italicisation and case.
:::I don't quite understand the following point. Do you mean to show only the top half? If so, one can use [[Template:CSS image crop]] or similar to display only the top half, as on the right. I've retained the bottom half in the image in case anyone wants to use it as an example.
:::Lastly, is it correct that Split-biquaternion is on the left column? Seems all the other splits are on the right. Was Split-biquaternion and Biquaternion accidentally swapped?

::{{ping|Cmglee}} Thank you for the updates. A first post has been placed at [[Galois connection]] where it is apparent that two lattices are in correspondence. The comment about confusing notation refers to the ordered pairs (a,b) in the group lattice. These numbers refer to the List of small groups but really are unnecessary for identifying the groups. Your note about split-biquaternion in the left column, while split-quaternion and split-complex are in the right, asks if a mistake has been made! No, the inclusions are correct. The terminology is explained at [[split algebra]]s. The only non-split algebras in the lattice are quaternions and complex numbers. — [[User:Rgdboer|Rgdboer]] ([[User talk:Rgdboer|talk]]) 21:36, 4 June 2025 (UTC)

== Log and angle ==

[[File:Log-pole-x_1.svg|right|thumb|200px]]
[[File:Hyperbolic_sector.svg|right|thumb|200px]]
;Article(s):
: [[Hyperbolic sector#Hyperbolic logarithm]]
;Request:
:In the article-section [[Hyperbolic sector#Hyperbolic logarithm]] one finds the following text:
"To accommodate the case of negative logarithms and the corresponding negative hyperbolic angles, different hyperbolic sectors are constructed according to whether ''x'' is greater or less than one. A variable right triangle with area 1/2 is <math>V = \{(x, 1/x), \ (x,0), \ (0,0)\} .</math> The isosceles case is <math>T = \{(1,1),\ (1,0),\ (0,0)\}.</math> The natural logarithm is known as the area under ''y'' = 1/''x'' between one and ''x''. A positive hyperbolic angle is given by the area of 
<math>\int_1^x \frac{dt}{t} + T - V.</math> A negative hyperbolic angle is given by the ''negative'' of the area <math>\int_x^1 \frac{dt}{t} + V - T.</math> This convention is in accord with a negative natural logarithm for ''x'' in (0,1)."

The object is to show that hyperbolic sector area to y = 1/x is the same as the log area. There are two cases: x in (0,1) and x > 1. The method uses addition and subtraction of right triangles. Illustrations are requested to show the equality of areas. — [[User:Rgdboer|Rgdboer]] ([[User talk:Rgdboer|talk]]) 22:35, 6 June 2025 (UTC)
;Discussion:
:I can't think of a way to show that the areas are equal. Only after drawing this, I realised that I could prove it only if ''S'' is the midpoint of ''OR''. In the above diagram, if ''S'' is at 1, ''R'' must be at 2, unless ''b'' can be shown to equal ''d''.
:Can you sketch, perhaps on paper, how you could explain it? Cheers, '''[[User:cmglee|cm&#610;&#671;ee]]'''&#9094;[[User_Talk:cmglee|&#964;a&#671;&#954;]] 22:43, 7 June 2025 (UTC)
::Ok, your diagram does combine the two given. Some of your variables are supposed constant: S = (1,0) so that P = (1,1). Then 0PS is triangle T given in the text. Next R = (x. 0) so Q = (x, 1/x) so triangle 0QR is the variable triangle called V in the text. Both of these triangles have area 0.5 . The argument is similar to a [[tangram]] puzzle where blocks are moved around. Here one triangle is added to a figure, then the other triangle removed. Since they both have area ½ the area after the addition and subtraction is the same as area before. Try considering only x > 1 first (as in your illustration) since complications arise due to [[signed area]]s in the general case. — [[User:Rgdboer|Rgdboer]] ([[User talk:Rgdboer|talk]]) 21:57, 8 June 2025 (UTC)
[[File:Visual proof hyperbolic sector area.svg|thumb|Updated]]
::Reading about Tangrams led me to [[Tiling puzzle]] which is more accurate here, except for shapes changing while area is constant. Using the notation you have provided, the proof runs as follows:
POQ = PSRQ + POS &minus; QOR. Then since area POS = area QOR, conclude area POQ = area PSRQ. — [[User:Rgdboer|Rgdboer]] ([[User talk:Rgdboer|talk]]) 22:17, 10 June 2025 (UTC)

:I'll redraw it with triangle T as in the article. '''[[User:cmglee|cm&#610;&#671;ee]]'''&#9094;[[User_Talk:cmglee|&#964;a&#671;&#954;]] 10:06, 11 June 2025 (UTC)

::{{ping|cmglee}} But your notation is more concise, just the labels P, Q, R, S. The lower case letters are of course superfluous. The article text can be altered with the OPQRS argument. — [[User:Rgdboer|Rgdboer]] ([[User talk:Rgdboer|talk]]) 21:43, 11 June 2025 (UTC)
:::Thanks, {{ping|Rgdboer}} I've updated it using your hint. It now works for any two points in the first quadrant, not just for {{nowrap|''x'' &gt; 1}}. '''[[User:cmglee|cm&#610;&#671;ee]]'''&#9094;[[User_Talk:cmglee|&#964;a&#671;&#954;]] 22:46, 11 June 2025 (UTC)
::Thank you cmglee for a splendid image of a complex notion. The OPQRS geometry makes unnecessary the assumption that P=(1,1). The naturalness of the notation clarifies the argument. The reversed orientation of negative areas need not confuse the introduction here of geometry referring to some ideas of calculus. The reference to a book by [[Isaak Yaglom]] shows this argument is not original research. — [[User:Rgdboer|Rgdboer]] ([[User talk:Rgdboer|talk]]) 21:20, 12 June 2025 (UTC)

;Article(s):
: [[Provisional Government of Saskatchewan]], [[List of Canadian flags]]
;Request:
: Hi! I was wondering if someone can kindly please vectorize the flag and coat of arms of Provisional Government of Saskatchewan? The flag was designed by [[Louis Riel]] and the description of the flag by Father Vital Fourmond (who was a witness to the provisional government's proclamation on 19 March 1885) is found on both pages linked above. The flag consists of the design of an old flag of France with a blue [[Escutcheon (heraldry)|heraldic shield]] with three [[Fleur-de-lis|Fleurs-de-lis]] though Riel altered this design by placing the [[Immaculate Heart of Mary]] (a Catholic symbol) on the shield. Although Father Fourmond described just the flag, it appears that by using a design with a heraldic shield, Riel had also created the coat of arms for the provisional government even if it wasn't his intention. The coat of arms on the PNG version of the flag uses a [[User:Sodacan|Sodacan]]-style for the shield and Fleurs-de-lis, the Immaculate Heart on the PNG version uses File:Immaculate Heart of Mary.svg but the design of that clashes with the Sodacan style for the shield and Fleurs-de-lis so I ask that for the SVG version, a Sodacan-style version of the Immaculate Heart is used instead. I have added SVG Sodacan-style versions of the designs to use as bases so the request can be done more quickly.
