How sneeky of him to sneek in sine, cosine, tanjent and not referencing them in his concept :DI just saw that. Here is a pdf explaining the technique:
What irks me most is this quote. "Classical trigonometry" has been thoroughly proven correct, and he acts like it is wrong. What he's done is not a new thing: he's just using a few changes of variables.Once you learn the five main rules of rational trigonometry and how to simply apply them, you realise that classical trigonometry represents a misunderstanding of geometry.
I stand corrected; I should have called it "silly" instead.Hurkyl said:To be fair, the mathematics is not nonsense: it's the suggestions that this is a new thing, and that it's clearly superior to classical trigonometry.
I'd have thought that this idea is so bad that it could only have come from the American educational system, but lookee there I was wrong.Mathematics students have cause to celebrate. A University of New South Wales academic, Dr Norman Wildberger, has rewritten the arcane rules of trigonometry and eliminated sines, cosines and tangents from the trigonometric toolkit.
