In this unit you’ll investigate the concept of irrational numbers. You’ll examine some examples of commonly used irrational numbers such as Pi (3.14159265…), 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.
