True or False: The domain of trigonometric functions can be restricted to any one of their branch(not necessarily principal value) in order to obtain their inverse function.

$\begin{array}{1 1} True \\ False \end{array} $

1 Answer

Ans - True
By choosing the proper interval with the same span as that of its corresponding
principal interval we can fix the domain.
That is for example principal interval of \(sin^{-1}x\) is \((-\frac{\pi}{2},\frac{\pi}{2})\).We can fix any of theintervals,\((\frac{\pi}{2},\frac{3\pi}{2})\:\:or\:(\frac{3\pi}{2},\frac{5\pi}{2})\)........ as the range of \(sin^{-1}x\)
