New Trig Method

    I haven't been here for a long time, so sorry if this was already posted:


    Dr Norman Wildberger has devised a new method of trigonometry that gets rid of sin, cos, tan (and the like) functions and uses algebra instead. It's supposedly straight forward, more accurate in a lot of cases, and more consistant with basic math.

    it uses properties called quadrance and spread.

    Does anybody know anything about this? Is it credible?
