Multiple Choice

Find the derivative of the function. $g ( x ) = 9 \sin ( x ) \cdot \tan x$

A) $g' ( x ) = 9 \cos ( x ) \cdot \tan x + 9 \sin ( x ) \cdot \csc ^ { 2 } x$
B) $g '( x ) = 9 \cos ( x ) \cdot \tan x + 9 \sin ( x ) \cdot \sec ^ { 2 } x$
C) $g '( x ) = 9 \cos ( x ) \cdot \tan x - 9 \sin ( x ) \cdot \cot x$
D) $g' ( x ) = 9 \cos ( x ) \cdot \tan x + 9 \cos ( x ) \cdot \cot x$
E) $g '( x ) = 9 \cos ( x ) \cdot \tan x - 9 \sin ( x ) \cdot \sec ^ { 2 } x$
