Complex Numbers
Complex numbers extend the number system beyond real numbers by introducing an imaginary unit, ‘i’, where i² equals -1. They are essential in solving polynomial equations and have applications in various mathematical and scientific fields, encompassing both real and imaginary components
After watching the AJMaths revision videos on complex numbers I will be able to:
- Understand How and Why We Use Complex Numbers
- Add and Subtract Complex Numbers
- Multiply Complex Numbers Together
- Find the Complex Conjugate
- Divide Complex Numbers
- Solve Quadratics With Complex Roots
- Solve Cubics and Quartics With Complex Roots
- Answer Exam Questions on Complex Numbers for A Level Further Maths
