@jdoe0001 did you see it?

So "TRUE" - Thanks!

jdoe0001 · Answer

now you know why is called a RADIAN :)

when the ARC made by the central angle, EQUATES the RADIUS
that angle is called a RADIAN
because of its relationship with the RADIUS

Oh, you might get annoyed with me, but I have one more question for you!

jdoe0001 · Answer

ok

anonymous · Answer

What are the coordinates of the terminal point determined by t = (20π)/3?

jdoe0001 · Answer

20/3 is a so-called "improper fraction"
if we make it a mixed type, then it'd be

6 2/3   or $\bf 6\pi \cfrac{2}{3} \implies 3(2) \cfrac{2\pi}{3}$

anonymous · Answer

so the coordinates are (1/2 , √3/2)???

jdoe0001 · Answer

that means 3 times 2pi
and then 2pi/3 more after that, that is
