In this unit you’ll investigate the concept of irrational numbers. You’ll examine some examples of commonly used irrational numbers such as Pi (), , the ‘Golden Ratio’ and the natural logarithm ‘e’ and explore where irrational numbers have applications in the real world. You’ll then take a closer look at the nature of both Pi and irrational roots or surds and how they work.
The unit includes an AMSI Interactive unit called ‘Investigating Irrational Numbers’
