Talk:Mnemonics in trigonometry

(untitled)
To me a nemonic is supposed to provide an easy way to help you remember something. It shouldn't be hard to remember or hard to remember how to use. The second nemonic, I feel, is quite complicated, has much information buried in it, is hard to learn how it all goes together, and takes a significant amount of memory to remember how to use all its various parts. Given that, is it really a nemonic?

A second thing I want to do is give for consideration the nemonic I learned way back when we used paper trig tables. Sorry, I do not know a reference for it. And I can not edit it in, because I don't know the markup here on Wiki.

It is: OH,  AH,  Oh-Ah,  Ah-Oh,  HA,  HO  (Say it moderately fast).

Sine, cosine, tangent, cotangent, secant, cosecant are: O/H,  A/H,  Oh/Ah,  Ah/Oh,  H/A,  H/O.

Unlike the soa-cah-toa nemonic it gives all six common functions. But I like to teach only the 1st three, OH, AH, Oh-Ah (simple enough), or even only the first two, OH AH -- and have them (students) memorize only Sin, Cos, and Tan -- then have them learn and understand that tan= sin/cos and the last three are inverses of the 1st three.

It might sound a bit like a tongue twister at first, but it only took a my high school trig class about 15 minutes to learn it and a good part of that time was laughter -- and it is silly enough to be memorable. I still use it after 45+ years and some of my today's students have picked it up too as the one they prefer (over soh cah toa).

grammar
My biggest problem in understanding these mnemonics is the grammar. I had trouble visualizing the descriptions of the relationships between the listed equations, and it was little help that the related visuals were not cited well and thus difficult to identify. I'm lawyer brained not math brained, I'd really appreciate if someone who understood the typed descriptions could rewrite them to paint the picture more clearly. Thank you for reading. — Preceding unsigned comment added by Jgraham916 (talk • contribs) 22:11, 14 June 2017 (UTC)

Merge All Students Take Calculus
I don't think there's enough content on All Students Take Calculus to justify a separate article. It's small enough that it would fit here nicely. I'm not sure "All Students Take Calculus" is the most notable mnemonic for this, anyways. (I learned ACTS, going clockwise.) -Apocheir (talk) 18:18, 4 February 2018 (UTC)

Sourcing
My suggestion: All sinners take confession.Pbrower2a (talk) 21:06, 22 August 2020 (UTC)

Please only include mnemonics on this page that can be reliably sourced, preferably to educational texts. If we included every possible expansion of ACTS, this page would be a mile long. -Apocheir (talk) 22:02, 2 September 2020 (UTC)

Mnemonic Suggestion
The way I learned to remember the trig functions was from Saxon Math, and it goes like "Oscar had a hold on Arthur". Granted, I'm sure the response will be that the mnemonic is already mentioned with "Angie" instead of Arthur, but it is still a suggestion.
