\frac{d}{d x} (4 - cos (x))

sin (x)

Solution steps

\frac{d}{d x} (4 - cos (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (4) - \frac{d}{d x} (cos (x))

\frac{d}{d x} (4) = 0

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

= 0 - (- sin (x))

Simplify

= sin (x)

x \to 2 + lim (4 - x^{2})

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

(6.3) (9.6)

y^{^{''}} - 4 y^{^{'}} + 5 y = 0

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