Complex Numbers

Many of us learn to count by visualising a horizontal number line – negatives to the left and positives to the right, zero in the middle. With complex numbers we introduce a vertical number line of ‘imaginary’ numbers. But it turns out these imaginary numbers are not just ‘made up’ but have many applications in the real world and are important in a wide range of Math courses. This online Complex Numbers course introduces a range of new techniques to describe and work with complex numbers and is a stand-alone course with some cross-over to Trigonometry.
