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

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

Solution steps

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

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)

\frac{d}{d x} (x ln (4 y) + x + y)

\int 6 x^{\frac{3}{2}} d x

x \to \infty lim (4^{x} + 5)

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

\int \frac{1}{x ^{2} - 2 x + 10} d x
