derivative of

f (x) = - 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)

x \to 16 lim (x - 164)

\frac{\partial}{\partial x} (arctan (x^{2} + y^{2}))

\frac{x ^{5}}{4 - x ^{4}}

y^{^{'''}} - 7 y^{^{''}} - 8 y^{^{'}} = 0

f (x) = \frac{2}{x ^{2}}, at x = 1
