I want tell you that the people wo creat that page really know how important colors play their roles in web-surfers' eyes. Simple but good looking.
But I don't find it fun at all, perhaps because I am not well today.

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.

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.
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.

I stand corrected; I should have called it "silly" instead.
There's a big difference between a correct, but silly approach and a nonsensical approach.
