Question

Find the quotient of the complex numbers. Express your answer in trigonometric form.
z1 = 12(cos(320 degrees) + isin(320 degrees))
z2 = 4(cos(80 degrees) + isin(80 degrees))

A. z1 = 48(cos(240 degrees) + isin(240 degrees))
B. z1 = 3(cos(40 degrees) + isin(40 degrees))
C. z1 = 12(cos(140 degrees) + isin(140 degrees))
D. z1 = 3(cos(240 degrees) + isin(240 degrees))

Answer 1

divide the number in front, subtract the angles
that is all

Answer 2

this is homework I know this

Answer 3

answers don't really make sense because you have written \(a_1\) twice, so i assume they are meant to be \(\frac{z_1}{z_2}\)

Answer 4

So its D.

Actually @bynowSPAMER its practice work :)

Answer 5

yeah, it is D you can pretty much do it in your head

Answer 6

Yeah! Thanks :)
