Section 2.4
Question 48

13/(1 - i)

Multiply numerator and denominator
by the complex conjugate of denominator.

Yes?

13/(1 - i) • (1 + i)/(1 + i)

(13 + 13i)/(1 - i + i - i^2)

(13 + 13i)/(1 - (-1))

(13 + 13i)/2

(13/2) + (13/2)I

You say?

How is 52 done?

 

[MathLover1]

correct

you can use decimals
6.5 + 6.5 i

 

[nycmathguy]

correct

you can use decimals
6.5 + 6.5 i

Cool. I feel confident about Section 2.5.
