Express the Function as a Sinusoid of the Form Y $$y = 3 \sin ( 4 x ) + 4 \cos ( 4 x )$$

Express the function as a sinusoid of the form y = a sin (bx + c) .
- $$y = 3 \sin ( 4 x ) + 4 \cos ( 4 x )$$

A) $y = 5 \sin \left( 4 x - \sin ^ { - 1 } \left( \frac { 4 } { 5 } \right) \right)$ )
B) $y = 5 \sin \left( 4 x - \cos ^ { - 1 } \left( \frac { 4 } { 5 } \right) \right)$
C) $y = 5 \sin \left( 4 x + \cos ^ { - 1 } \left( \frac { 4 } { 5 } \right) \right)$
D) $y = 5 \sin \left( 4 x + \sin - 1 \left( \frac { 4 } { 5 } \right) \right)$
