derivative of

f (x) = 3 cos (x)

- 3 sin (x)

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the common derivative:

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

= 3 (- sin (x))

Simplify

= - 3 sin (x)

x \to 0 + lim (3 sin (x) ln (x))

\frac{d}{d x} (x + (x^{6})^{3})

y = \frac{3 x ^{5} + 7}{x ^{3}}

t^{2} \frac{d x}{d t} = 2 t x + 1

\int \frac{1}{x ^{2} ( 1 + \frac{1}{x} ) ^{3}} d x
