question 443

Multiple Choice

Write the complex number in trigonometric form r(c $$r ( \cos \theta + i \sin \theta )$$ ) , with $$\theta$$ in the interval [0 $$\left[ 0 ^ { \circ } , 360 ^ { \circ } \right)$$
- $- 4 - 4 i \sqrt { 3 }$

• A) \(8 \left( \cos 290 ^ { \circ } + i \sin 290 ^ { \circ } \right)\)
• B) \(4 \left( \cos 240 ^ { \circ } + i \sin 240 ^ { \circ } \right)\)
• C) \(8 \left( \cos 240 ^ { \circ } + i \sin 240 ^ { \circ } \right)\)
• D) \(8 \left( \cos 180 ^ { \circ } + i \sin 180 ^ { \circ } \right)\)
