Why is it 1

[–] [email protected] 27 points 2 weeks ago* (last edited 2 weeks ago)

It was freely chosen for simplicity.

If you choose another R, the other sides (x and y) become R*cos(th) and R*sin(th)

I don't understand what is harmful about the unity circle either.

Any circle could have its radius technically be 1, as long as you set the units of measurement so that 1 equals the radius of the circle.

units? what are those? I never use units, or pay attention to capitals. pure math ftw, baby!

Pure math uses units. Like they say "1 unit"

[–] [email protected] 2 points 2 weeks ago

Sometimes the units are given cute names like "wiggly waggly units" to make physicists cringe. Acknowledging a unit with cute names when the unit is not important is entertaining.

Because it's a unit circle.

for the same reason that rulers start with 1, it would be utterly pointless to use anything else.

[–] [email protected] 6 points 2 weeks ago (1 children)

Your ruler starts with 1? How do you measure stuff between 0 and 1?

[–] [email protected] 2 points 2 weeks ago (2 children)

those are unlabeled, have you ever seen a ruler?

[–] [email protected] 3 points 2 weeks ago

I am fascinated, can you show a picture

[–] [email protected] 3 points 2 weeks ago

Zero is not unlabelled lol
