look up any word, like swag:
used to remember trigonometry but also if said in very high pitched voice "SOCHATOA" can really annoy a maths teacher !!! or even "SOHCAHTO" .... "A"
Mr E: I think were gunna need trig....

Gareth: SOHCAHTO...?!?!?!

Callum: A

Gareth And Callum: SOHCAHTOA!!!!

Mr E: grrr Gareth move !!! blah bla blah scraping a C blah bla blah

1) Trigonometry; 2) An acronym, the formula used in trigonometry classes so that students can remember trigonometric functions. It stands for: Sine=Opposite/Hypotenuse, Cosine=Adjacent/Hypotenuse, Tangent=Opposite/Adjacent.
Hey Ed, remember that equation Ms. Lubar gave you in class? Just remember sohcahtoa and you'll ace the test!

A mnemonic device to aid in recalling the relationships of the main trigonometric functions.

<S>ine is <O>pposite the <H>ypotenuse
<C>osine is <A>djacent to the <H>ypotenuse
<T>angent is <O>pposite over <A>djacent.

Sometimes written as "soh cah toa."
When analyzing a right triangle, remember "sohcahtoa."

helps you remeber you cos,sin and tan.

Some Old Hippie Caught Another Hippie Tripping On Acid
i totally forgot what formula to use for tan, but then i remembered the acid poem (sohcahtoa)

Used in Geometry.
My teacher told me to remember it by: (S)ome (O)ld (H)ippie (C)aught (A)nother (H)ippie (T)rippin (O)n (A)cid.
Teacher: Okay so you remember SOH CAH TOA?

Us: you mean, some old hippie caught another hippie trippin on acid?

Teacher: Yes.

Trig mnemonic for:

Sine = Opposite/Hypotenuse
Cosine = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent

Problem is, who can remeber how to spell this supposed Indian Princess name? Much better mnemonic is Sally Can Tell (sine/cosine/tangent in the vertical column) Oscar/Has, A/Hard, On/Always (opposite/hypotenuse, adjacent/hypotenuse/, opposite/adjacent, also vertically).
Socohtoa, Socahtohoa, Socotoah, Sohcahtoa, ??? Might as well remember the whole order of functions...

Some Old Hippie Caught Another Hippie Tripping On Acid.

Mnemonic device for SOHCAHTOA, referring to the trigonometric method of finding the sine, cosine, and tangent of a right triangle.
During Math quiz day, Johnny remembered SOHCAHTOA. The kid next to him actually did it.
