Use the product-to-sum formulas to write the expression below as a sum or difference.
$\sin ( 8 \theta ) \cos ( 6 \theta )$

A) $\frac { 1 } { 2 } ( \cos ( 2 \theta ) + \cos ( 14 \theta ) )$
B) $\frac { 1 } { 2 } ( \sin ( 2 \theta ) + \cos ( 14 \theta ) )$
C) $\frac { 1 } { 2 } ( \sin ( 14 \theta ) + \sin ( 2 \theta ) )$
D) $\frac { 1 } { 2 } ( \cos ( 2 \theta ) - \cos ( 14 \theta ) )$
E) $\frac { 1 } { 2 } ( \sin ( 14 \theta ) - \sin ( 2 \theta ) )$
