In this lesson, we will learn how to represent a complex number in polar form, calculate the modulus and argument, and use this to change the form of a complex number.

Lesson Plan

Students will be able to

write a complex number represented on an Argand diagram in polar form,
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.
