Solve the equation: 2 cos θ - 3 = -5 within 0 ≤ θ < 2π.

• θ = π/3

• θ = π/2

• θ = π

• θ = 2π

Solve for θ: sin θ = 0.

• θ = 0 + 2kπ

• θ = π/2 + 2kπ

• θ = π + 2kπ

• θ = 3π/2 + 2kπ

What is the general solution for θ when sin θ = 1/2?

• θ = π/6 + 2kπ

• θ = π/3 + 2kπ

• θ = π/4 + 2kπ

• θ = π/2 + 2kπ

What is the solution for θ when cos θ = -1?

• θ = 0

• θ = π

• θ = 2π

• θ = 3π
