derivative of

\frac{( 1 - x )}{( x + 2 )}

- \frac{3}{( x + 2 ) ^{2}}

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

\frac{( - 1 ) ( x + 2 ) - 1 \cdot ( 1 - x )}{( x + 2 ) ^{2}} : - \frac{3}{( x + 2 ) ^{2}}

= - \frac{3}{( x + 2 ) ^{2}}

x^{3} y^{^{'}} + 4 x^{2} y = e^{- x}

\int \frac{1}{cot ( x )} d x

g (x) = x + x^{3}

\int \frac{1 + cos ( 2 x )}{2} d x

f (x) = \frac{sec ( x ) + tan ( x )}{sec ( x ) - tan ( x )}
