Support · Mathematics Extension 2 11–12 – Year 12 · Introduction to complex numbers
Support Define and use complex numbers in polar or modulus–argument form that expresses a complex number in terms of its modulus and argument, z = r(cosθ + isinθ), where r is its modulus and θ is an argument of z, and represent complex numbers in this form on the complex plane
