\frac{d}{d x} (\frac{sin ( x )}{x + 1})

\frac{cos ( x ) ( x + 1 ) - sin ( x )}{( x + 1 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{sin ( x )}{x + 1})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( sin ( x ) ) ( x + 1 ) - \frac{d}{d x} ( x + 1 ) sin ( x )}{( x + 1 ) ^{2}}

\frac{d}{d x} (sin (x)) = cos (x)

\frac{d}{d x} (x + 1) = 1

= \frac{cos ( x ) ( x + 1 ) - 1 \cdot sin ( x )}{( x + 1 ) ^{2}}

Simplify

= \frac{cos ( x ) ( x + 1 ) - sin ( x )}{( x + 1 ) ^{2}}
