Answer each of the following questions in one word or one sentence or as per exact requirement of the question:

If x > 1, then write the value of in terms of tan^{–1} x.

Given x > 1

⇒ tan θ > 1

Multiplying by -2,

Subtracting with π,

We know that

Put tan θ = x

For x > 1,

Since x = tan θ

⇒ θ = tan^{-1} x
