Complex numbers and complex planes
Now that we know the basics of imaginary numbers, let's expand our knowledge and learn about another concept that is closely tied to imaginary numbers – complex numbers, a number that is consisted of a real part, and an imaginary part. In this section, we will learn what makes up a complex number, as well as how to plot on a complex plane.
Basic Concepts
- Evaluating and simplifying radicals
- Solving quadratic equations using the quadratic formula
- Nature of roots of quadratic equations: The discriminant
Related Concepts
