The domain of the function fx=log1sinx

a
R--π,π
b
R-nπ|n∈Z
c
R-2nπ|n∈z
d
-∞,∞

detailed solution

Correct option is B

fx      is  defined   for      log1sinx≥0or     1sinx≥1   and    sinx≠0or     sinx≠0                                  1sinx≥1  for  all   xor   x≠nπ,  n∈ZHence,   the   domain  of  fx  is  R-nπ.  n∈Z.
