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 realize 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.
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.
