question 189

Multiple Choice

Write the complex number in trigonometric form r(c $$r ( \cos \theta + i \sin \theta )$$ ) , with $$\theta$$ in the interval [0 $$\left[ 0 ^ { \circ } , 360 ^ { \circ } \right)$$
- $3 \sqrt { 3 } + 3 i$

• A) \(6 \left( \cos 30 ^ { \circ } + i \sin 30 ^ { \circ } \right)\)
• B) \(6 \left( \cos 60 ^ { \circ } + i \sin 60 ^ { \circ } \right)\)
• C) \(6 \left( \cos 150 ^ { \circ } + i \sin 150 ^ { \circ } \right)\)
• D) \(6 \left( \cos 330 ^ { \circ } + i \sin 330 ^ { \circ } \right)\)
