Question

2sin(-60⁰)*tg(п/3)- cosП

Answer 1

Ответ:

2*(-√(3)/2)*√(3)-(-1)= -2

Answer 2

Let's break down the expression step by step:

1. First, calculate sin(-60°): sin(-60°) = -sin(60°) = -√3/2

2. Next, calculate tan(π/3): tan(π/3) = √3

3. Finally, calculate cos(π): cos(π) = -1

Now, plug these values back into the original expression:

2sin(-60°) * tan(π/3) - cos(π) = 2 * (-√3/2) * √3 - (-1)

Now, simplify:

= -√3 * √3 - (-1) = -3 + 1 = -2

So, the value of the expression 2sin(-60°) * tan(π/3) - cos(π) is -2.
