Yes, probably a search of "soh cah toa" would turn up an answer.

I was suggesting that if the questioner did a little investigating, he would find what SOHCAHTOH meant. Many texts include that mnemonic.

By the name that you put for the topic, "soh cah toa", I believe you want to know what "soh cah toa" means.
Ultraglide does tell you how to answer your question. However, I can understand that the connection may not be obvious unless specifically spelled out. Probably there is a site that spells it out but I will list it here:
For a right triangle
. B
. *
. * *
. c * *
. * * a
. * *
. * *
. A*************C
b
The sin of A = a/c (the opposite side / the hypotenuse)
.
The cos of A = b/c (the adjacent side / the hpotenuse)
.
The tan of A = b/a (the opposite side / the adjacent side)
.
If you know what the above means, great. If not, ask and we can show you an example.
The connection is "soh cah toa" is just an acronym for "sine opposite hypotenuse cosine adjacent hypotenuse tangent opposite adjacent".
.
Just insert the words "equals" and "over":
.
sine equals opposite over hypotenuse cosine equals adjacent over hypotenuse tangent equals opposite over adjacent"

You need to express more clearly what your question is. If you want to find how to determine the sine, cosine, and tangent, you will find the explanation in any introductory text and certainly on the net.
