derivative of

- cos (x)

sin (x)

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

= - (- sin (x))

Simplify

= sin (x)

- \frac{1}{x ^{2}}

f (x) = x^{2} + 1

x^{2} - 24 x - 12

f (x) = x^{2} + 3 x

f (x) = \frac{x + 1}{x - 1}
