θ

Explanation:

Recall from our trigonometric identities that

sin

2

θ

+

cos

2

θ

=

1

. Then the expression becomes:

sin

2

θ

+

cos

2

θ

tan

2

θ

=

1

tan

2

θ

We also know from the definition of cotangent that

cot

θ

=

1

tan

θ

. Squaring both sides, we obtain

cot

2

θ

=

(

1

tan

θ

)

2

=

2

tan

2

θ

=

1

tan
