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

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

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

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

Simplify

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

- 2 x^{2}

\int 9 x^{2} - 8 x d x

\int \frac{3}{1 + 9 x ^{2}} d x

\int \frac{y ^{2} - 4}{y} d y

\frac{d}{d x} (\frac{x ^{5} - 8 x ^{3} + x + 6}{x})
