Question

d/dx (2sin(x)cos(x))

Answer 1

what is finding in this please explain in detail or send photo thanks you

Answer 2

$since \: 2 \sin(x) \cos(x) = \sin(2x) \\ \\ therefore \\ \\ \frac{d}{dx} (2 \sin(x) \cos(x) ) \\ \\ = \frac{d}{dx} \sin(2x) \\ \\ = \cos(2x) \frac{d}{dx} 2x \\ \\ = 2 \cos(2x) \\ \\ hope \: it \: helps...$
