\frac{d}{d x} (11 cos (x))

- 11 sin (x)

Solution steps

\frac{d}{d x} (11 cos (x))

Take the constant out:

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

= 11 \frac{d}{d x} (cos (x))

Apply the common derivative:

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

= 11 (- sin (x))

Simplify

= - 11 sin (x)

y = \frac{x ^{2} - 1}{x ^{2} + x + 1} (1)

\frac{d}{d x} (2 x + e^{x})

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

\frac{1}{2 x - 1}

x \to \infty + lim (e^{x} + 3)
