Step-by-step explanation:
Use
f
−
1
f
(
x
)
=
x
that is valid for any function y = f(x) that is
bijective in an (infinitesimal)
∈
- neighborhood
(
x
−
∈
,
x
+
∈
)
of x.
Here, it is
sin
−
1
sin
(
π
6
)
=
π
6
.
It is important to note that
sin
(
π
6
)
=
sin
(
13
6
π
)
=
1
2
and, while
sin
−
1
(
1
2
)
= the conventional principal value
π
6
,,
sin
−
1
sin
(
π
6
)
=
π
6
and
sin
−
1
sin
(
13
6
π
)
=
13
π
6
.
