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)

f (x) = 8 x^{2} + 11 x, at x = 7

3 x - 4 y = 7

(4, - 43)

y = 2 x + 5

3 sin^{2} (x)
