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

\frac{1}{1 + cos ( x )}

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

\int e^{- s t} t cos (t) d t

\frac{5}{s ( s ^{2} + s + 1 )}

\int_{- 2}^{2} 4^{x} d x

\frac{( d y )}{( d x )} = 8 x^{(3)} + 6 x^{(2)}

15 x ln (4 x)
