The Correct Option is
B
Solution and Explanation
Explanation:
Given,
sec
2
θ
+
tan
2
θ
=
3
...(i)Subtracting 1 from both sides in equation (i) we get,
sec
2
θ
+
tan
2
θ
−
1
=
3
−
1
(
∵
sec
2
θ
−
1
=
tan
2
θ
)
⇒
tan
2
θ
+
tan
2
θ
=
2
⇒
2
tan
2
θ
=
2
⇒
tan
2
θ
=
1
⇒
tan
θ
=
1
Now,
cot
θ
=
1
tan
θ
=
1
Hence, the correct option is (B).
