Represent complex numbers on the complex plane

What you'll learn

1. Plot complex numbers on the complex plane and identify the real and imaginary axes.
2. Convert a complex number from rectangular form (a + bi) to polar form r(cos theta + i sin theta).
3. Convert a complex number from polar form to rectangular form.
4. Explain why rectangular and polar forms represent the same complex number.
