derivative of

- 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)

\int \frac{3 x - 2}{x ^{2} - 6 x + 10} d x

\frac{d}{d x} (1 0^{x l n (x) - x})

\int 2 e^{x} sin (x) d x

x \to 0 lim ((- 3 x + 1)^{\frac{5}{x}})

\int (x + 2)^{13} d x
