derivative of

\frac{sin ( x )}{x}

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

Solution steps

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

\frac{d}{d x} (sin (x)) = cos (x)

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

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

Simplify

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

\int \frac{12}{x ^{4}} d x

arctan (\frac{x}{2})

\frac{d y}{d x} - 50 y = - y^{2}

\int_{2}^{x} \frac{1}{8} (x - 2) d x

n = 1 \sum \infty (- 6)^{n} x^{n}
