Lesson: Modulus of a Complex Number Mathematics

Students will be able to

• understand that the modulus of a complex number is equal to the square root of the sum of the squares of the real and imaginary parts of the number,
• find the modulus of a complex number in Cartesian form,
• understand that the modulus of a complex number is the distance of the complex number from the origin in a complex plane,
• understand that the modulus of the complex conjugate is equal to the modulus of its complex number,
• use the properties of the modulus of complex numbers to solve problems.
