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
< 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).
