\frac{d}{d x} (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}

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

(x^{2} - 2 x) (2 x - x^{2})

\frac{\partial}{\partial t} (t e^{s t})

\frac{d}{d x} ((x - 1) tan (x) + x sin (π x))

(2 x y) d x + (x^{2} - 1) d y = 0
