\frac{d}{d x} (3 x^{3} + cos (x))

9 x^{2} - sin (x)

Solution steps

\frac{d}{d x} (3 x^{3} + cos (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (3 x^{3}) + \frac{d}{d x} (cos (x))

\frac{d}{d x} (3 x^{3}) = 9 x^{2}

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

= 9 x^{2} - sin (x)

x \to 2 lim (3 x + a)

x^{2}, 25, 0, 5

\int x^{2} + 4 d x

\frac{d}{d x} ((x - a) (x - b) (x - c))

\frac{d y}{d t} + \frac{4 y}{200 + 3 t} = 8
