Is There a Trick to Remembering the Trigonometric Functions?

You are aware, I hope, that the etymology you posted about SOH CAH TOA was completely made up.

We have adopted tags recently that are intended to do just that. B - beginner, I - intermediate, A - advanced. We haven't used them much here in the math sections, but they are used a fair amount in the physics sections.

Yeah. I just noticed 'em a few days ago and came across the explanation. In regards to the fictional nature of Soh Cah Toa the Indian Chief, it was meant to extend the absurdity of the device to increase its effectiveness. World-class mnemonists memorize insane amounts of information with silly vignettes they picture in their minds eye. In my opinion, there should be many more devices to use... medical students live and die by them. As for this being a 'B', all I can say is:

Limit of the differential quotient - slope of the tangent line - mu. Can we let this exchange die now?

The story of the Native American should be considered fiction. It's a pun.
