Description

The format of the course is narrated explanations and calculations. Its exactly the way that I've explained these things to hundreds of students and how I would explain them if you were sitting next to me right now!

The course covers the very basic aspects of:

  • Pythagoras
  • Angles (degrees, minutes and seconds)
  • Trigonometry
  • Coordinates
  • Whole circle bearings
The course assumes that you have zero knowledge of these topics so its perfect for you if you are:
  • completely new to the topics
  • need a refresher
  • are struggling with these or related topics
Who is the target audience?
  • This course is meant for anyone who would like to understand the basics of of angles, Pythagoras, trigonometry, coordinates and whole circle bearings.
