Share the animation of the interactive resource with students. It shows an overview of concepts and abilities to be developed. Start by reviewing number sets studied before, and then encourage students to extend the use of number sets with imaginary numbers, which, together with real numbers, form a robust set of numbers called complex numbers. Then, explain the importance and application of these numbers in everyday life. End with the study of the applications of De Moivre’s formula based on the exponentiation of complex numbers.
