Question

2 sin 2 π/3 cos π/2​

Answer 1

Answer:

The Answer will be zero.

Answer 2

Answer:

The value will be 0.

Step-by-step explanation:

Given equation is:

$2\,sin(\dfrac{\pi}{3})cos(\dfrac{\pi}{2})$

$=2sin(60\°)\cdot cos(90\°)$

We know the trigonometric values:

$sin(60\°)=\dfrac{\sqrt 3}{2}\\cos(90\°)=0$

Hence:

$=2\cdot \dfrac{\sqrt 3}{2}\cdot 0\\=0$
