Question

WILL AWARD METALS!!
Convert the polar representation of this complex number into its standard form:
z=6(cos300 degrees + isin300degrees)

a) 3(sqrt 3) - 3i
b) -3-3(sqrt 3i)
c) 3(sqrt 3)- 3(sqrt 3i)
d) 3-3(sqrt 3i)

thank you in advance!

Answer 1

@Thesn1 could you help me please?

Answer 2

it s d

Answer 3

300degree = 360 degree +( - 60 degree )
so replace cos 300 and sin 300 by cos(-60) and sin(-60)
after we have cos(-60)=0.5 and sin(-60)=0.5sqrt3
then replace all and d) appear
good luck

Answer 4

sin(-60)=-0.5sqrt3 :D

Answer 5

so the answer is d?

Answer 6

yeaaaah
