Question

Sin pi/2+ 2 cos pi+ ctg 2 pi/6= Помогите решить пожалуйста!!!

Answer 1

Sin pi/2+ 2 cos pi+ ctg 2 pi/6=1+2*(-1)+(√3)²=1-2+3=2

Answer 2

Solving the Equation

To solve the equation sin(pi/2) + 2*cos(pi) * ctg(2*pi/6), we can break it down step by step.

First, let's calculate the values of the trigonometric functions involved in the equation.

1. sin(pi/2): - The sine of pi/2 is equal to 1. - Source: 2. cos(pi): - The cosine of pi is equal to -1. - Source: 3. ctg(2*pi/6): - The cotangent of 2*pi/6 can be simplified to cot(π/3) which is equal to √3. - Source: Now, we can substitute these values back into the original equation:

1 + 2 * (-1) * √3

Solving this, we get:

1 - 2√3

So, the value of the given expression sin(pi/2) + 2*cos(pi) * ctg(2*pi/6) is 1 - 2√3.
