Solving Trig Equations

Solve sinθ = ½

• θ = π / 6, 7π / 6

• θ = π / 6, 5π / 6

• θ = 5π / 6, 7π / 6

• θ = 7π / 6, 11π / 6

Solve 2cos²θ -1=0

• θ = π /4, 7π /4

• θ = π /4, 3π /4

• θ = 3π /4, 5π /4

• θ = π /4, 3π /4, 5π /4, 7π /4

Solve 2cosθ - 4=0

• No solution

• θ = π/3 , 5π/3

• θ = π/6 , 11π/6

• θ = 2π/3 , 4π/3
