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.
In this lesson we learn how to use exact values to convert complex numbers from Polar form to standard form, so we don’t have to write them with rounded decimal numbers.
In this lesson you learn how to convert a complex number from polar form to standard form. In fact, we show you how to convert from standard to polar then back to standard again.
In this lesson we explain how to convert a complex number from standard form to polar form. We show you the theory behind it all first and then we explain how to do it quickly.
This lesson we talk about how the argument has to be between -180 to 180 degrees, so if the complex number has a negative imaginary part then it will have a negative argument.
In this lesson we talk about how to find the argument of z – the angle between the line segment joining the origin to z and the positive x axis.
In this lesson we talk about how to find the modulus of a complex number.
