Question

Sin pi - cos^2 pi/6 * tg pi/3

Answer 1

Ответ:Sin pi/6 = 1/2

cos pi/6 = √3/2

tg pi/3 = sin pi/3 / cos pi/3

Таким образом, 3*1/2 + 2*√3/2 - √3/2 / 1/2 = 3/2

Answer 2

Let's break down the expression step by step:

1. sin(pi) = 0
2. cos^2(pi/6) = (sqrt(3)/2)^2 = 3/4
3. tan(pi/3) = sqrt(3)

Now, plug in these values:

sin(pi) - cos^2(pi/6) * tan(pi/3) = 0 - (3/4) * sqrt(3)

Finally, let's simplify the expression:

sin(pi) - cos^2(pi/6) * tan(pi/3) = - (3/4) * sqrt(3)

So, the simplified value of the expression is: - (3/4) * sqrt(3).
