derivative of

x sin (\frac{4}{x})

sin (\frac{4}{x}) - \frac{4 cos ( \frac{4}{x} )}{x}

Solution steps

\frac{d}{d x} (x sin (\frac{4}{x}))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = sin (\frac{4}{x})

= \frac{d x}{d x} sin (\frac{4}{x}) + \frac{d}{d x} (sin (\frac{4}{x})) x

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

\frac{d}{d x} (sin (\frac{4}{x})) = - \frac{4 cos ( \frac{4}{x} )}{x ^{2}}

= 1 \cdot sin (\frac{4}{x}) + (- \frac{4 cos ( \frac{4}{x} )}{x ^{2}}) x

Simplify

1 \cdot sin (\frac{4}{x}) + (- \frac{4 cos ( \frac{4}{x} )}{x ^{2}}) x : sin (\frac{4}{x}) - \frac{4 cos ( \frac{4}{x} )}{x}

= sin (\frac{4}{x}) - \frac{4 cos ( \frac{4}{x} )}{x}

\int_{0}^{1} 2 π (x) (x - x^{2}) d x

\frac{d}{d x} (lo g_{7} (\frac{x ^{4}}{5 x + 11}))

x^{2} (1 - 4 x)

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

\frac{d}{d x} (x a^{2} + x^{2})
