rectangular form  6(cos(150) + isin(150))  a.(3,√3,-3) B.(-3,√2,3) C.(3,√2,-3)  D.(-3,√3,3)

anonymous · Answer

your job is to evaluate $\cos(150)$ and $\sin(150)$ then multiply the result by 6

anonymous · Answer

none of the above are correct

anonymous · Answer

for a variety of reasons
first, standard form is not ordered pairs, it is $a+bi$
second, $\cos(150)=-\frac{\sqrt{3}}{2}$ and $\sin(150)=\frac{1}{2}$

anonymous · Answer

the correct answer is 
$$-3\sqrt{3}+3i$$

thx

anonymous · Answer

still none of the answers are right, because a complex number in rectangular form is $a+bi$ not $(a,b)$
whoever wrote this is very confused
