  1. 8.3Polar Form of Complex Numbers

  2. Complex #: a + bi • Where a is the real number part and bi is the imaginary number part.

  3. Complex Plane Graph: 2 + 3i 3 – 2i

  4. Absolute Value of a complex number z = a + bi (modulus) is:

  5. Find modulus: • 3 + 4i • -7 + 24i

  6. If z = a + bi and we connect that point to the origin, we get:

  7. Therefore:

  8. Write in polar form: • 1 + i • 3 + 4i

  9. Write in polar form:

  10. Express in rectangular form (keep going!)
