When you multiply two complex numbers in polar form, what happens to the angles?
prisoha [69]

The angles get added.

Let <em>z</em> = <em>r</em> exp(<em>i</em> <em>θ</em>) and <em>w</em> = <em>s</em> exp(<em>i</em> <em>φ</em>). Then

<em>zw</em> = <em>rs</em> exp(<em>i</em> <em>θ</em>) exp(<em>i</em> <em>φ</em>) = <em>rs</em> exp(<em>i</em> (<em>θ</em> + <em>φ</em>))

Please explain step-by-step. If you don't explain, don't even bother answering.
Andre45 [30]

Answer:

<u>45°</u>

Step-by-step explanation:

From the diagram :

  • ∠AOC = ∠AOB + ∠BOC
  • 96 = 9x - 75 + 8x - 67
  • 17x - 142 = 96
  • 17x = 238
  • x = 238/17
  • x = 14

Finding ∠BOC :

  • ∠BOC = 8x - 67
  • ∠BOC = 8(14) - 67
  • ∠BOC = 112 - 67
  • ∠BOC = <u>45°</u>

What is the distance between the two points? (-18, -6) &amp; (-18,-1)
Hitman42 [59]

Answer:

5

Step-by-step explanation:

D² = ( x2 - x1 )² + ( y2 - y1 )²

= [ (-18) - (-18) ]² + [ (-1) - (-6) ]²

= ( -1 + 6 )²

D² = ( 5 )²

hence, D = 5
