Question

4cos pi/3 - 2 sin pi/3​

Answer 1

Ответ:

4cos π/3 - 2sin π/3 = 4 • 1/2 - 2 • √3/2 =

= 2 - √3

Объяснение:

π/3 = 60⁰

cos60° = 1/2

sin60° = √3/2

Answer 2

Ответ:

$2 - \sqrt{3}$

Объяснение:

$4 \cos(\pi \div 3) - 2 \sin(\pi \div 3)$

$4 \cos\binom{\pi}{3} - 2 \sin \binom{\pi}{3}$

$4 \times \frac{1}{2} - 2 \times \frac{ \sqrt{3} }{2}$

$2 - \sqrt{3}$

Answer 3

To simplify the expression 4cos(π/3) - 2sin(π/3), you can use the values of the cosine and sine of π/3, which are known trigonometric values.

cos(π/3) = 1/2 sin(π/3) = √3/2

Now, substitute these values into your expression:

4cos(π/3) - 2sin(π/3) = 4(1/2) - 2(√3/2)

Now, simplify the expression:

2 - √3

So, 4cos(π/3) - 2sin(π/3) simplifies to 2 - √3.
