New angle on trigonometry

Apparently the mathematical study of triangles has just got a whole lot simpler. Could it be the end of this?

Sounds good, but way too late for me! I still have nightmares in which I’m fumbling through tables of sines and cosines. I’m old enough (and my school backward enough) not to have even had the benefit of calculators!

Unfortunately the new method involves algebra — I was shit at that too.
