derivative of

y = 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}

f (x) = \frac{cos ( x )}{2 + sin ( x )}

\int cos^{3} (8 - x) sin (8 - x) d x

\frac{d y}{d x}, x y = 5

n = 0 \sum \infty (\frac{5}{6})^{n}

\frac{d}{d x} (x^{3} + 3 x^{2} + 1)
