Complex numbers and vectors are both important areas of study within the senior secondary mathematics curriculum. They are particularly significant for those students wishing to undertake further study in mathematics or in disciplines that require a strong background in mathematics. These students typically study specialist or advanced mathematics subjects in their senior mathematics curriculum. However, the advent of more sophisticated hand- held technologies over the past decade or so has meant that students from mainstream function, algebra and calculus courses also come across complex numbers as roots to certain types of algebraic equations in the analysis of polynomial functions.
