Multiple Choice

Which of the following expressions is equivalent to $$\frac { 3 \tan 8 x + 3 \tan 8 y } { 1 - \tan 8 x \tan 8 y }$$ ? (x ? ?n,y ? ?n,where n is a whole number) ?

A) $\frac { 8 \cot 3 x + 8 \cot 3 y } { \cot 3 x \cot 3 y - 1 }$
B) $\frac { 3 \cot 8 x + 3 \cot 8 y } { \cot 8 x \cot 8 y + 1 }$
C) $$\frac { 3 \cot 8 x + 3 \cot 8 y } { \cot 8 x \cot 8 y - 1 }$$
D) $\frac { 3 \cot 8 x - 3 \cot 8 y } { \cot 8 x \cot 8 y - 1 }$
E) $\frac { 8 \cot 3 x + 8 \cot 3 y } { \cot 3 x \cot 3 y + 1 }$
