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

2 cos (4 x)

Solution steps

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = cos (2 x), g = sin (2 x)

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

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

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

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

Simplify

(- sin (2 x) \cdot 2) sin (2 x) + cos (2 x) \cdot 2 cos (2 x) : 2 cos (4 x)

= 2 cos (4 x)

\int \frac{6}{x ^{5}} d x

x \to - 7 - lim (x^{2} + \frac{4}{x + 7})

x \to 2 lim (3 x^{2} - 4 x + 6)

\frac{\partial}{\partial x} (ln (ln (x)))

y^{^{'}} = 8 x + y
