\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)

(7 - 6 x)^{\frac{1}{2}}, at x = - 1

\int_{1}^{2} \frac{1}{x ^{3}} d x

f (x) = x^{2} + x, (2, 6)

\frac{d}{d x} (cos^{3} (x) + sin^{3} (x))

x \to \infty lim (\frac{3}{2})
