question 19

Multiple Choice

Solve the equation for $\theta$ $( 0 \leq \theta \leq 2 \pi )$ . For some of the equations you should use the trigonometric identities listed in this section. Use the trace feature of a graphing utility to verify your results. $\cos 2 \theta + 3 \cos \theta + 2 = 0$

• A) \(\frac { 2 \pi } { 3 } , \frac { 4 \pi } { 3 } , \pi\)
• B) \(\frac { 2 \pi } { 3 } , \frac { 4 \pi } { 3 } , 2 \pi\)
• C) \(0 , \frac { 2 \pi } { 3 } , \frac { 4 \pi } { 3 } , \pi\)
• D) \(0 , \frac { \pi } { 3 } , \frac { 4 \pi } { 3 }\)
• E) \(0 , \frac { \pi } { 3 } , \frac { 4 \pi } { 3 } , \pi\)
