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

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

3.8 t e^{2.4 t}

\frac{\partial}{\partial x} (\frac{- k y}{x ^{2} + y ^{2}})

5 - 3 t

x^{^{'}} + 2 x = e^{- 2 t} cos (t)

\int y ln (y) d y
