Question

1 - cos √3/2 разделить на 2?

Answer 1

Cos4x=√3/2
4x=⁺₋arccos√3/2 + 2πn, n∈Z
4x=⁺₋π/6+ 2πn, n∈Z, разделим обе части на 4
x=⁺₋π/24 +πn/2,n∈Z

Answer 2

оооооооооооооооооооооооо

Answer 3

To calculate the expression (1 - cos(√3/2)) / 2, we can follow these steps:

1. Find the value of cos(√3/2). Using a scientific calculator or reference table, we can determine that cos(√3/2) is approximately 0.5.

2. Substitute the value into the expression: (1 - 0.5) / 2

3. Simplify the expression: (0.5) / 2 = 0.25

Therefore, (1 - cos(√3/2)) / 2 is equal to 0.25.
