Answer 1

Answer:

Step-by-step explanation:

A mixed number consists of an integer and a proper fraction:

$a(b)/(c)$

where the numerator is less than the denominator (b < c).

A terminating decimal is a decimal that ends. For example, 1/2 = 0.5.

A repeating decimal is a decimal that repeats forever. For example, 1/3 = 0.33333...

You must use 2, 3, and 4 exactly once. Try different combinations and see which ones result in a terminating decimal, and which one results in a repeating decimal.

Perform the division and leave the result in trigonometric form.

Answers

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° )
