derivative of

\frac{2 x + 1}{x + 3}

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

y = \frac{1}{x}, y = 4 x, y = \frac{1}{4} x

f (t) = t cos (t) - sin (t)

\frac{d}{d x} (\frac{6}{x ^{4}} + \frac{1}{x ^{2}})

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

\int (x^{6} + 1) d x
