    IMPORTANT… Students… This presentation is designed to be used in class as part of a  guided discovery sequence. It is not self-explanatory! Please  use it only for revision purposes after having taken the class.  Simply flicking through the slides will teach you nothing. You  must be actively thinking, doing and questioning to learn! Instructors… You are free to use this presentation in your classes and to  make any modifications to it that you wish. All I ask is an  email saying where and when it is/was used. I would also  appreciate any suggestions you may have for improving it.  thank you, David .
