Continued with questions from 3.9 using deMoivre's Theorem to expand complex numbers to a given power.
HW Complete Ex. 3.9 Q.6-10

Today we introduced 3.9 DeMoivre's Theorem and used it to expand complex numbers.

The video here is a solution to a Leaving Cert Higher Level Project Maths question. It summarises what we have covered in class over the last few days. Take your time to view it if you are finding this section difficult.

HW: Include Ex.3.9 Q. 6 and 7

Corrected HW and did an example from 3.7 on Polar Form. We then started 3.8 Polar Products and Quotients.
Finally we introduced Radian Measure for angles.

HW: Questions from Ex. 3.8

Today we continued with our work on Polar Form of a Complex Number from Ex. 3.7. 

HW: 

• Re-look at Ex. 3.7 2, 3, 4
  
• You might also look at the 2 short videos belo on Polar Form
  

Today we introduced 3.7 Polar Form of a Complex Number.

Today we continued with our study of 3.6 Polynomials with pairs of conjugate roots. In particular we looked at solving cubic equations with conjugate imaginary roots.

HW: Include Ex. 3.6 Q.6, 7, 8, 10

Today we answered HW questions from 3.4 on Argand diagram and 3.4 Complex Number Transformations. We then introduced 3.6 Conjugate root theorem.


HW: Include Ex. 3.6 Q.1-3

Started 3.5 Transformations of complex numbers

HW: Ex. 3.5 Q.1-5 and 10
