Nope, I've never seen that before. I learned the trig functions as "wrapping functions", the rolling circle, and the application to triangles was derived later, when there was no possibility of confusion over what bit was which, I think.

That's the way I've always known them...to me it's a much more intuitive method (which helped me not one bit when I swapped my numerator and denominator for tangent and cotangent today on a test... SPLENDID!)
