Answer:
(x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)
Step-by-step explanation:
The rule for CCW rotation through an angle α is ...
(x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))
So, for α = 210°, the rule becomes ...
(x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)
It is less than 1, because 1/2 is also .5, so that is already less than 1 whole.
Also, any number under 6 divided by 6 (for example: 5 divided by 6, 3 divided by 6) has to be less than one, since 6 can't evenly go into a number lower than it.
