\( \sin ( 7 x ) + \sin ( x ) = \) _______

Preview Enter your answer as an expression. 

Example: \( 3 x ^ { \wedge } 2 + 1 , x / 5 , ( a + b ) / c \) 

Be sure your variables match those in the question 

Answer

\( \sin ( 7 x ) + \sin ( x ) = 2\sin\frac{7x+ x}{2}\cos\frac{7x- x}{2}= 2\sin{4x}\cos{3x}\)
