WildTrig13: Why spreads are better than angles

[unshakenpeace]

Hasn't rational trigonometry only recently been introduced in 2005?

When you listen to this guy you can see why most students think math is tough. He is using the most complicated way I have ever seen to explain this stuff.

Teachers have to be able to teach, not just spout rote from never really understood memories. Remember, those who can-do; those who can't-teach

@ZijiXiji

I disagree. I think this is much simpler than standard trigonometry. This isn't hard to understand in any way.

Is the angle 25.941176470588235294117647058­82352...?

I like that I can precisely calculate the spread, whereas for the angle, I must appeal to some external approximate source.
