• write a complex number in polar form given its modulus and argument,
• calculate the modulus and argument of a complex number written in Cartesian form,
• write a complex number in Cartesian form given its modulus and argument,
• find the modulus and argument of a complex number represented in polar form,
• change between Cartesian and polar forms of a complex number,
• write the conjugate of the complex number in polar form.
