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.

[-] bizarroland@fedia.io 12 points 11 months ago

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"

[-] within_epsilon@beehaw.org 2 points 11 months 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.

[-] ryannathans@aussie.zone 6 points 11 months ago

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

[-] Swedneck@discuss.tchncs.de 2 points 11 months ago

those are unlabeled, have you ever seen a ruler?

[-] mexicancartel@lemmy.dbzer0.com 3 points 11 months ago

Zero is not unlabelled lol
