derivative of

x sin (\frac{5}{x})

sin (\frac{5}{x}) - \frac{5 cos ( \frac{5}{x} )}{x}

Solution steps

\frac{d}{d x} (x sin (\frac{5}{x}))

Apply the Product Rule:

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

f = x, g = sin (\frac{5}{x})

= \frac{d x}{d x} sin (\frac{5}{x}) + \frac{d}{d x} (sin (\frac{5}{x})) x

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

\frac{d}{d x} (sin (\frac{5}{x})) = - \frac{5 cos ( \frac{5}{x} )}{x ^{2}}

= 1 \cdot sin (\frac{5}{x}) + (- \frac{5 cos ( \frac{5}{x} )}{x ^{2}}) x

Simplify

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

= sin (\frac{5}{x}) - \frac{5 cos ( \frac{5}{x} )}{x}

\frac{d}{d x} (a x sin (x) + b x cos (x))

\int e^{8 x - 7} d x

\int x^{2} \cdot 7 x - 5 d x

\int \frac{5}{x 36 - 25 ln ^{2} ( x )} d x

\frac{\partial}{\partial x} (ln (y^{x^{2}}))
