derivative of

f (x) = - 2 sin (2 x)

- 4 cos (2 x)

Solution steps

\frac{d}{d x} (- 2 sin (2 x))

Take the constant out:

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

= - 2 \frac{d}{d x} (sin (2 x))

Apply the chain rule:

cos (2 x) \frac{d}{d x} (2 x)

= cos (2 x) \frac{d}{d x} (2 x)

\frac{d}{d x} (2 x) = 2

= - 2 cos (2 x) \cdot 2

Simplify

= - 4 cos (2 x)

\int x^{4} - 2 x^{2} + 1 d x

\int (8 x - 9) d x

\int \frac{2 - 3 x ^{2}}{5 x ^{3} - 10 x + 5} d x

\frac{\partial}{\partial x} (x^{2} y e^{\frac{y}{z}})

\frac{\partial}{\partial x} (x + y)
