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

- \frac{1}{2 x ^{2}}

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Quotient Rule:

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

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

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

\frac{d x}{d x} = 1

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

Simplify

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

= - \frac{1}{2 x ^{2}}

\int_{0}^{\frac{π}{4}} sin (4 t) d t

d er i v a t i v e ln (\frac{x - 2}{x + 2})

\frac{d}{d x} ((\frac{x ^{3} - 1}{x ^{3} + 1})^{8})

f (x) = sin^{3} (3 x)

f (t) = cos (2 t)
