Evaluate \( Cosec (cos^{-1} \dfrac{8}{17})\)

Evaluate tan^-1(tan 12)

Evaluate tan^-1(tan 4)

Evaluate tan^-1(tan 2)

Evaluate \( tan^{-1}(tan \dfrac{9\pi}{4})\)

Accepted Answer

Given tan^-1(tan 1)

But we have tan^-1(tan x) = x if x ϵ [\( \dfrac{-\pi}{2},\dfrac{\pi}{2}\)]

By substituting this condition in given question

Tan^-1(tan 1) = 1
