Answer:
Step-by-step explanation:
We know that,
csc
2
θ
=
cot
2
θ
+
1
...
...
.
(
1
)
.
(
csc
2
θ
)
3
=
(
cot
2
θ
+
1
)
3
.
Since,
(
x
+
y
)
3
=
x
3
+
y
3
+
3
x
y
(
x
+
y
)
,
we have,
csc
6
θ
=
(
cot
2
θ
)
3
+
1
3
+
3
(
cot
2
θ
)
(
1
)
(
cot
2
θ
+
1
)
,
=
cot
6
θ
+
1
+
3
cot
2
θ
(
csc
2
θ
)
...

.
[
∵

,
⇒
csc
6
θ
=
cot
6
θ
+
3
cot
2
θ
csc
2
θ
+
1
