\frac{d}{d x} (5 + cos (x))

- sin (x)

Solution steps

\frac{d}{d x} (5 + cos (x))

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (5) + \frac{d}{d x} (cos (x))

\frac{d}{d x} (5) = 0

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

= 0 - sin (x)

Simplify

= - sin (x)

y^{^{'}} + 2 y = x y^{2}

f (x) = (2 x - 8)^{4} (x^{2} + x + 1)^{5}

y = x^{3} - 10 x^{2} + 21 x, y = - x^{3} + 10 x^{2} - 21 x

e^{\frac{3}{x}}

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