Значения функции y при различных углах:

• y(0) = 1/2 * cos(0) - 3 = 1/2 * 1 - 3 = -2.5
• y(π/6) = 1/2 * cos(π/6) - 3 = 1/2 * (√3/2) - 3 = -2.133
• y(π/3) = 1/2 * cos(π/3) - 3 = 1/2 * 1/2 - 3 = -2.25
• y(π/2) = 1/2 * cos(π/2) - 3 = 1/2 * 0 - 3 = -3
• y(2π/3) = 1/2 * cos(2π/3) - 3 = 1/2 * (-1/2) - 3 = -3.25
• y(5π/6) = 1/2 * cos(5π/6) - 3 = 1/2 * (-√3/2) - 3 = -3.133
• y(π) = 1/2 * cos(π) - 3 = 1/2 * (-1) - 3 = -3.5
• y(7π/6) = 1/2 * cos(7π/6) - 3 = 1/2 * (-√3/2) - 3 = -3.133
• y(4π/3) = 1/2 * cos(4π/3) - 3 = 1/2 * (-1/2) - 3 = -3.25
• y(3π/2) = 1/2 * cos(3π/2) - 3 = 1/2 * 0 - 3 = -3
• y(5π/3) = 1/2 * cos(5π/3) - 3 = 1/2 * (1/2) - 3 = -2.75
• y(11π/6) = 1/2 * cos(11π/6) - 3 = 1/2 * (√3/2) - 3 = -2.133
• y(2π) = 1/2 * cos(2π) - 3 = 1/2 * 1 - 3 = -2.5
