13pi/6

I know that 5pi/6 is one of them

Answer 1

\[\frac{ 13 \pi }{ 6 }\]

Answer 2

\[\frac{ 13 \pi }{ 6 }=2\pi+\frac{ \pi }{ 6 }\]

Answer 3

why dont the others work

Answer 4

and do any of the others work

Answer 5

okay so then the only two that can fit in are 5pi/6 and 13pi/6

Answer 6

are you sure because i know that it can go into other quadrants as a reference angle as well

Answer 7

pi-5pi/6=pi/6

Answer 8

yes you are correct.
