In this video lesson I explain what complex conjugates are, as well as some of their properties. I list some examples of complex numbers, with their conjugates alongside them and explain the general rule of forming the conjugate. Then I show some notation with putting a bar over a number, which means taking its complex conjugate. Finally, I use an example to show that a complex number times its conjugate is always real. For more details see the video!
