In this tutorial we use complex numbers to factorise a cubic polynomial. h
In this tutorial we go through how to use the factor theorem to factorise a polynomial of degree 3.
In this tutorial I show you how to use complex numbers to factorise a polynomial that you normally can’t factorise.
In this video we show you the proof of how when two complex numbers multiply each other, the resulting magnitude equals the the product of the two original magnitudes and the argument equals the sum of the two original arguments.
So you are okay with squaring complex numbers. Can you square root one? Magic Monk shows you how.
In this tutorial we learn how to raise complex numbers to the nth power using pascal’s triangle.
Today we learn how to divide two complex numbers and express the answer in a+bi using conjugates.
In this tutorial we introduce the idea of conjugates with complex numbers, and talk about what happens when you multiply two conjugates together.
In this tutorial we talk about how to divide complex numbers in polar form using a simple formula.
In this tutorial we talk about how to multiply two complex numbers together when they are in polar form using an easy formula.
