Quick Reference

• Multiplication and division in polar form
  This leaflet explains how complex numbers in polar form can be multiplied and divided. In polar form, these operations are particularly simple to carry out.
• The Argand diagram
  This leaflet explains how an Argand diagram is used to provide a pictorial representation of a complex number.
• The Argand Diagram
  This leaflet explains how complex numbers can be represented pictorially using an Argand Diagram. There are accompanying videos.
• The form r(cos(t) + j sin(t))
  This leaflet explains how a complex number can be written in the form z=r(cos(t) + j sin(t)).
• The modulus and argument of a complex number
  This leaflet explains how to calculate the modulus and argument of a complex number. There are accompanying videos.
• The polar form
  This leaflet explains the polar form of a complex number. It defines the modulus and argument of a complex number.
• The polar form of a complex number
  This leaflet explains what is meant by the polar form of a complex number. There are accompanying videos.

Video

A transcript of each video should be available in the Teach Yourself section above.

These videos require Windows Media Player (v10).

Please note: You may experience trouble with more recent upgrades to Internet Explorer (now v.7) and Media Player (now v.11). These no longer support streaming from the mms servers used by mathcentre, so we are recommending that you uninstall IE7 (IE6 lies underneath) and replace the new version of WMP with the fully functioning v.10 (you may need to find a download via google after uninstalling v.11). All those that have done this have reported back that everything is working again.
