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

- sin (x) - 1

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

\frac{d x}{d x} = 1

= - sin (x) - 1

(x - 5)^{2} + (y - 3)^{2} = 18, (8, 6)

\int_{0}^{4} π (3 x)^{2} d x

f (x) = cos (tan (x))

y^{^{''}} + a y^{^{'}} + b y = t + e^{3 t}

x \to - 1 lim (ln (x + 1))
