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

4 sin (2 x)

Solution steps

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

Take the constant out:

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

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

Apply the chain rule:

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

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

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

= - 2 (- sin (2 x) \cdot 2)

Simplify

= 4 sin (2 x)

\frac{\partial}{\partial y} (y^{2} e^{x y - 3})

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

\int \frac{1}{- 2 y} d y

y = 3 sin (\frac{x π}{90})
