My geometry teacher asked me to find her some info on SOH-COH-TOA. I've
been unsuccessful on the WWW. If anyone can help I'd appreciate it
greatly.

Thanks.

SOH-CAH-TOA (or TOA-CAH-SOH) is a mnemonic used in Singapore to help
students remember the definitions of the trigonometrical ratios:

Sin = Opposite / Hypotenuse
Cos = Adjacent / Hypotenuse
Tan = Opposite / Adjacent

It is particularly easy to remember because in Hokkien (a Chinese
dialect spoken by many Singaporeans) TOA-CAH-SOH sounds like the Old
Aunty with a Big Foot.

Soh-Coh-Toa is a way of remembering sin, cosin, and tangent.
Sin of Hypotonus
Cosin of hypotonus
Tangent of ajacent

This should surely be:

SOH Sin is Opposite/Hypotenuse
CAH Cos is Adjacent/Hypotenuse
TOA Tan is Opposite/Adjacent
