What is Trigonometry? Is it a long and complex sounding word; is it a branch of mathematics; is it something that you learnt about but is of no relevance to you today?
Do you use trigonometry? Do you use a Global Positioning System (GPS)? If you answered yes to the second question, then your answer to the first question would also be yes!
Wikipedia defines trigonometry as:
The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.
But definitions seldom excite students in a class, because they often look for application and relevance. We’ve found some video resources that can help you put the concept of trigonometry in perspective and also add some fun to the class session.
