derivative of y=xsin(2x)

Solution

derivative of

y = x sin (2 x)

Solution

sin (2 x) + 2 x cos (2 x)

Solution steps

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

Apply the Product Rule:

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

f = x, g = sin (2 x)

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

\frac{d x}{d x} = 1

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

= 1 \cdot sin (2 x) + cos (2 x) \cdot 2 x

Simplify

= sin (2 x) + 2 x cos (2 x)
