derivative of

- cos (3 x) \cdot 3

9 sin (3 x)

Solution steps

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

Take the constant out:

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

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

Apply the chain rule:

- sin (3 x) \frac{d}{d x} (3 x)

= - sin (3 x) \frac{d}{d x} (3 x)

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

= - 3 (- sin (3 x) \cdot 3)

Simplify

= 9 sin (3 x)

\int \frac{1}{a x ^{2} + b x} d x

x \to 5 lim (8 x + ∣ x - 5 ∣)

2 sin (π x)

\int_{0}^{2} (x^{4} - 5 x^{3} + 2 x) d x

\int \frac{sin ( 2 x )}{43 + cos ^{2} ( x )} d x
