\frac{d}{d x} (\frac{3 x - 2}{2 x + 1})

\frac{3 x + 5}{( 2 x + 1 ) 2 x + 1}

Solution steps

\frac{d}{d x} (\frac{3 x - 2}{2 x + 1})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( 3 x - 2 ) 2 x + 1 - \frac{d}{d x} ( 2 x + 1 ) ( 3 x - 2 )}{( 2 x + 1 ) ^{2}}

\frac{d}{d x} (3 x - 2) = 3

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

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

Simplify

\frac{3 2 x + 1 - \frac{1}{2 x + 1} ( 3 x - 2 )}{( 2 x + 1 ) ^{2}} : \frac{3 x + 5}{( 2 x + 1 ) 2 x + 1}

= \frac{3 x + 5}{( 2 x + 1 ) 2 x + 1}

f (x) = - \frac{1}{x + 2}, at x = 3

\frac{\partial}{\partial x} (e^{x} cos (x))

f (x) = x^{2} + 5

\frac{d}{d x} (cos (2 x + π))

\int \frac{1}{( 1 - x ) ^{3}} d x
