Answer 1

Answer:

Answer:

$(1)/(2)$ ( cos40° + isin40°)

Step-by-step explanation:

To divide

$\frac{r_{1(cosx_(1)+isinx_(1)) } }{r_(2)(cosx_(2)+isinx_(2)) }$

= $(r_(1) )/(r_(2) )$ [ cos(x₁ - x₂) + isin(x₁ - x₂)

Given

$(2(cos90+isin90)/(4(cos50+isin50))$

= $(2)/(4)$ ( cos(90 - 50)° + isin(90 - 50)°

= $(1)/(2)$ ( cos40° + isin40° )
