derivative of

x sin (\frac{2}{x})

sin (\frac{2}{x}) - \frac{2 cos ( \frac{2}{x} )}{x}

Solution steps

\frac{d}{d x} (x sin (\frac{2}{x}))

Apply the Product Rule:

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

f = x, g = sin (\frac{2}{x})

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

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

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

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

Simplify

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

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

y = 4 x^{3} + x, x = 2, x = - 1, x

x \to - 2 lim (\frac{x - 1}{x + 2})

\frac{1}{y ^{2}} - \frac{3}{y ^{4}}

\int \frac{3 x}{4 - x} d x

\frac{10}{s ( s + 1 ) ( s + 10 )}
