Express the Function as a Sinusoid of the Form Y $$y = 7 \sin x - 2 \cos x$$

Multiple Choice

Express the function as a sinusoid of the form y = a sin (bx + c) .
- $$y = 7 \sin x - 2 \cos x$$

A) $y = \sqrt { 53 } \sin \left( x - \cos ^ { - 1 } \left( \frac { 2 } { \sqrt { 53 } } \right) \right)$
B) $y = 53 \sin \left( x + \sin ^ { - 1 } \left( \frac { 2 } { \sqrt { 53 } } \right) \right)$
C) $y = \sqrt { 53 } \sin \left( x + \sin - 1 \left( \frac { 2 } { \sqrt { 53 } } \right) \right)$
D) $y = \sqrt { 53 } \sin \left( x - \sin - 1 \left( \frac { 2 } { \sqrt { 53 } } \right) \right)$
