derivative of

sin (2 x) cos (2 x)

2 cos (4 x)

Solution steps

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

Apply the Product Rule:

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

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

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

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

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

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

Simplify

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

= 2 cos (4 x)

x \to - \infty lim (0 \cdot (x))

y = 2 (x - 4)^{2}, (2, 8)

cos (x), \frac{1}{3} π

x + 1 = y^{2}, y^{2} + 2 x = 10

12 y^{^{''}} + 5 y^{^{'}} - 3 y = 0
