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

\frac{sin ( x )}{x}

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the chain rule:

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

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

\frac{d}{d x} (x) = \frac{1}{2 x}

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

Simplify

- 2 (- sin (x) \frac{1}{2 x}) : \frac{sin ( x )}{x}

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

y ln (x) ln (y) d x + d y = 0

\int \frac{2 ^{x}}{3 ^{x}} d x

\frac{d}{d x} (6 x cos (x^{2}))

\int_{1}^{e} \frac{x ^{2} + 1}{x} d x

y^{^{''}} = - 25 y
