Gave Willingly was taught to me in college, believe it or not. (Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Gray, White - I still remember it 60 years later...) Anyway, I was taught, even earlier than the resistor color code, "All Students Take Calculus" which perhaps isn't as useful today, since trig is (apparently) no longer the "gateway" into precalculus. I suggest an encyclopedia isn't an appropriate place for insults, even if the intent isn't malicious.

mentioned in a half sentence. There is one sentence about "The sine and cosine functions are one-dimensional projections of uniform circular motion" but this should be a whole section. There is no discussion of the relation of trigonometric functions to vectors, but this should also be a whole section. There is one example of a Fourier series, but this should again be a whole section. The section

in this context. I think any such discussion should clearly and explicitly point out that (a) the half-tangent is itself a "trigonometric function" of angle, and (b) it's an alternative representation to angle measure, in terms of which other trigonometric functions can be described rationally, making it to a substantial extent a way to

one has to be careful about which sheet of the covering space one is on, because a periodic function of period 2π is being described in terms of a periodic function of period π. Hardy does this by continuation using a quarter period, but that's needlessly complicated. I'll try to track down a source that explicitly uses this approach.
1609:”, begins, “If the acute angle θ is given, then any right triangles with an angle of θ are similar to each other.” How about, “Any two right triangles with the same acute angle θ, are similar to each other.” (I include a comma after a long subject of a sentence, such as here, for legibility.) Also, could “to each other” be removed? 1069:. But in any event, this is awfully mild and lighthearted to be called "outrageous", given all of the actually outrageous things in the world. (By comparison, your mnemonic joking about rape is quite gratuitously crass and sexist, and perhaps racist, and any teacher presenting it today could expect to be fired.) – 803:
citation in the footnotes. If you add a source used for just one claim, or a source used a few times but which is short enough to not need a page specified or where the pages used are the same for all cited claims, put it directly into a footnote. Feel free to also add textual notes to the 'notes' section. –

I'm still a bit concerned about this new section. I think it's a bit misplaced and somewhat misdirected. The half-tangent is well worth mentioning somewhere here, but the "analysis" section is not the right place in my opinion, and I think the way this one is currently written gives this undue weight
1086:
But Quantling makes a good point that "All Students Take Calculus" is better on other grounds. Moreover, poking into the literature, it doesn't appear that people actually favor one mnemonic over another to a great extent here, so we shouldn't imply that only one mnemonic exists. I've gone ahead and

et al., I have heard many people talk about "SOHCAHTOA". Although I don't have a citation at hand, I think it is improvement to the article to discuss SOHCAHTOA. Hopefully, someone will come up with a citation pronto and this will all be moot but, even if not, might we keep this discussion anyway?

with the comment "Sqrt(2)/2 is much more common than 1/sqrt(2) in the literature". Though I understand that √2/2 is more common, the line gives it twice. I wonder if it may help learners to know that both expressions are valid, should they come across the rarer form. Does anyone have any thoughts on

The second paragraf says, “The trigonometric functions most widely used in modern mathematics are the sine, the cosine, and the tangent functions. Their reciprocals are respectively the cosecant, the secant, and the cotangent functions, which are less used. Each of these six trigonometric functions
1323:
I'm not married to using the tangent half-angle substitution instead of the tangent substitution. But it seems to me that the former is a lot simpler, and many of the basic properties of the trigonometric functions (especially their period) are more obvious. Actually defining them via the tangent,
1041:
Perhaps we could replace "All Science Teachers (are) Crazy" with "All Students Take Calculus". The latter is slightly better to me as a mnemonic because it doesn't have the extra word "are", and it has the added advantage of avoiding the potentially offensive language. Personally, my general rule
1003:
I am astounded that Knowledge allows the mnemonic "All Science Teachers (are) Crazy". The term "crazy" isn't acceptable, is it? Sure it's outrageousness makes it memorable, but I can think of lots of unacceptable mnemonics. Like the resistor code Bad Boys Ravished (raped) Our Young Girls But Violet

Different countries and different authors had/have different conventions about this. In modern English language sources "tan" is the most common, partly because it is the only one supported by default in LaTeX. But if you look at work from France, Germany, or Russia, especially historical sources,

These were merged (a long time ago) because it was thought that most relevant material about any of them would be applicable to all of the others, many relevant features would be useful to compare from one to another, and important context was needed in common between them. People thought separate

You are editing the style of the article (if you do this for consistency purposes, your choice has to be discussed here at the Talk page, it doesn't matter if "the code looks prettier"). Another thing I should discourage you from doing is changing "trigonometric" to "trig"; you can't do that; the

I agree the analysis section should be later in the article. Hardy explicitly defines the trigonometric functions by integration, although he uses the tangent substitution which is algebraic rather than rational. Bourbaki defines the trigonometric functions using unitary representations of the

is too long and is distracting at this length near the top. The historical definition used for 2000 years between the 2nd century BC and at least the end of the 18th century, of "trigonometric lines" representing line segments with respect to a circular arc, is not discussed at all and is only

I edited the section "Radians versus degrees", lightly, for concision. "the images to the right there are not great and could probably be usefully moved or replaced, and the table's content also doesn't match the section, and it should be moved or modified." How should said images be moved or
1555:
Could “in modern mathematics” be changed to “today”? After all, these functions are by definition part of math, so the word “mathematics” is redundant. When it says “… cotangent functions”, could “functions” be removed, as it is obvious that these are functions? (More generally, can the word
829:
I don't understand what you mean. What kind of note are you trying to add? Feel free to mix textual notes in with the reference footnotes. If you get consensus here, e.g. if you plan to do a substantial rewrite of the article, you can probably do some amount of reformatting of the appendices.
1293:
I don't think it's undue weight to include several definitions of the trigonometric functions that have been used in analysis. I used Hardy, in particular, because he addresses the unsatisfactory nature of the usual definition in elementary calculus, and someone had complained about it.
1698:– the images to the right there are not great and could probably be usefully moved or replaced, and the table's content also doesn't match the section, and it should be moved or modified. Shortening the captions doesn't really make a significant improvement in my opinion. – 1629:
In the expression “Trigonometric function sin θ”, i think “Trigonometric function” is redundant (kind of like “in color” in “red in color”); anyone who knows what sine is, knows that it is a trig function. Also, in “sine function versus angle”, “function” is redundant.
1241:, which grew far beyond reasonable article scope and should probably be published somewhere external to Knowledge. It will take a lot of work, especially trimming, to salvage some parts as a Knowledge article at this point, and I got quite stalled on the project.) 969:
you will commonly find "tang" and "tg" as an alternative. The current text in the article is fine, but if someone can find a clear discussion of this it would also be fine to more explicitly describe the relative popularity and extent of these various symbols. –

The next sentence is, “Thus these six ratios define six functions of θ, which are the trigonometric functions.” This is a bit wordy, since the word “function” is repeated. How about “Thus these six ratios define the six trigonometric functions of

But in any case, if we're going to add a section about this, its details should be well sourced and its content should be broadly reflective of the way the topic is addressed in high-level sources about trigonometric functions or trigonometry.

Also, in said section, there is a long gap between the table, “Summary of relationships between trigonometric functions”, and the text above it; due to the pictures and their captions. This makes me want to shorten the captions. One caption

Interesting. I didn’t realise multiple mnemonics had been created. The one I learned as a 16-year old was “All Stations To Claremont” where Claremont was a well-known station on the railway line that served the largest city in the vicinity.

What parts of the article should be rewritten, and how? Also, what do you mean by “random words”? Also, in the expression “Trigonometric function sin θ”, would you agree that “Trigonometric function” is redundant, at least in said caption?

In the article, there are references in the notes section and another section of references in the references section. This error (if it is an error) makes it impossible to annotate the article. Please someone fix this bug

Personally, I think "All Science Teachers (are) Crazy" is pretty tame as far as old mnemonics go; even if "crazy" is one of those stigmatizing words we should be making an effort to say less often, it's not what I'd call
105: 1851: 124: 1573:"In modern mathematics" and "today" are not necessarily equivalent. "Modern mathematics" is quite old, actually. And yes, I agree with the removal of the word "function" when it appears later in the article. 34: 1693:
Anyway as for your specific questions: The sentences about similar triangles should be more substantially rewritten for clarity. I don't think your proposed changes are much better than what was there.

I was on this page and I became curious: why do tangent, cotangent, secant and cosecant all share a page while sine and cosine get their own? Why can't we move them all into one page?
915: 1787:
This is my read, and parts of "Definitions in analysis" could be reorganized into that section, like Euler's formula, with Bourbaki's definition left in the analysis section.
1612:
The next sentence is, “This means that the ratio of any two side lengths depends only on θ.” Could “This means that”, be replaced with “Therefore” or “Thus” or “That is,”?
504: 416: 50: 1896: 1866: 1881: 1024: 1771:
You mean, “In the complex plane” should be a first-order section, not a subsection, and should should be the first thing in the article, other than the intro?
167: 1841: 308: 1644:
Several parts of this article might benefit from a substantial rewrite, but trying to cut out random words from its sentences doesn't seem that helpful. –

I am editing this article heavily for concision, including making the wikicode more concise. I strongly feel that concise wikicode looks prettier. Okay?

It seems to me that the approach we are crediting to Bartle and Sherbert is very likely due to Landau. It would be nice to include a reference if so.
