Question

1. Find all angles θ , where - 2π < θ < 0, such that tan θ = sqrt3/3 .
2. Find all angles θ , where 360° < θ < 720°, such that sec θ = −2 and csc θ > 0.

Answer 1

1. tanθ = √3/3, θ = π/6 - π = - 5π/6 or θ = π/6 - 2π = - 11π/6. Both -5π/6 and - 11π/6 on interval (-2π, 0)
2. secθ = - 2, θ = 120°+360° = 480°. Answer is 480°
