Directions: Solve the following equations. ONE method of solution will be shown.

 1 If 0 < x < 2π, solve the equation:        2(cos x + 1) = 1

 2. If 0 < θ < 2π, solve the equation:        4 tan θ + 2 = 2 tan θ

 3. Solve the equation for x when 0 < x < 2π.        2 cos x + 3 = 0

 4. Solve for x to the nearest degree when 0º < x < 360º.        3(cos x - 1) = 3 - 4 cos x

 5. Find x when 0 < x < 2π :        4 sin2x - 1 = 0

 6. For 0º < x < 360º, solve the equation:        5 sin2x - 4 sin x - 1 = 0

 7. Find θ to the nearest degree if 0º < θ < 360º.        2 cos2θ - 4 cosθ - 5 = 0

 8 In the interval 0º < x < 360º, find all x values that satisfy the equation (to the nearest degree).

 9. In the interval [0º,360º], find all values of θ that satisfy this equation to the nearest degree.        3 cos2θ =2 - sin θ

 10. In the interval [0º,360º], find all values of x that satisfy this equation to the nearest tenth of a degree.
