OhMiGod, they killed Pricess SohCahToa!
Sine=Opposite/Hypotenuse
Cosine=Adjacent/Hypotenuse
Tangent=Opposite/Adjacent
It was CHIEF SohCahToa in my school....
God only knows how I passed trig, because I certainly don't!

Oh, and we'd have been given a big, fat F if we'd be caught with a calculator. They weren't allowed even in class, nevermind at a test.

SohCahToa got me through Trig and I passed on the info to my kid when he took Trig (somehow the teacher didn't mention it) and it got him through too, LOL.
Once you understand it's just ratios, it takes all the "mystery" out of it.
Wasn't that the volcanic island that blew up in the 1800's? ;)
Trig methods will still appeal more to the spatially-oriented than algebraic solutions.
There was this tribe of Indians in the old west who had a custom that whenever a couple was expecting, that the brave would venture into the wilderness, slay a mighty beast and bring the skin back to wrap the newborn in. It was supposed to bring the power and spirit of the slain animal to the new member of the tribe. Well, one particularly fertile year there were three couples expecting. The braves all went out into the wilderness about the same time to do their solemn duty to their newborn and to the tribe. The first brave went out and slew a grizzly bear and proudly returned with the skin to wrap his new baby boy in. The second brave went out and slew a cougar and proudly returned with the skin to wrap his new baby girl in. The third brave went to a special place he knew in the wilderness (there were those who suspected it was very close to the zoo), and slew a hippo, which he skinned. When he returned, he discovered that his wife had given birth to twins, a boy and a girl, which he proudly wrapped in the hippo skin.
This just goes to prove that age old adage (or is it a theorem?) Ready?
The squaw of the hippopatamus is equal to the sum of the squaws of the other two hides!
My favorite trig mnemonic is "Oscar Had A Heap Of Apples" (opposite/hypotenuse, adjacent/hypotenuse, opposite/adjacent, which codes for sine, cosine and tangent respectively).

To this day, I still remember that Tangent = Old A##
Sine=Opposite/Hypotenuse
Cosine=Adjacent/Hypotenuse
Tangent=Opposite/Adjacent

S=O/H sine=Opposite /Hypotenuse
C= A/H cosign=Adjacent/Hypotenuse
T=O/A Tangent = Opposite/Adjacent
.....70's thing... ya'll wouldn't understand..hahahahhaha
Yeah, but Oscar had a heap of apples...JFK
