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."

<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."

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!

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.

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...

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
