Question 113
Suppose that the sides $a$, $b$, $c$ of $\triangle ABC$, corresponding to the angles $A$, $B$, $C$ respectively, constitute a geometric sequence. Then the range of
$$
\frac{\sin A \cot C + \cos A}{\sin B \cot C + \cos B}
$$
is ( ).
$$
\frac{\sin A \cot C + \cos A}{\sin B \cot C + \cos B}
$$
is ( ).
