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!

Reference: NCERT: Class 10 – Chapter 8 – Introduction to Trigonometry

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.

  • Video: Trigonometry & GPS – This video by Discovery Channel explains how Global Positioning Systems use trigonometry to track location.
  • Video: Introduction to Trigonometry – This video by the Teaching Channel demonstrates how Ms. Tennis, an eight-grade teacher uses innovative strategies to introduce trigonometry to her students.
  • Video: Navigation Word Problem – This video by Khan Academy illustrates the steps to solve a trigonometry word problem related to navigation.

Passionate about everything related to education. I believe that the best kind of learning happens through play, experiments and fun! I love watching how children learn and love to implement play-based, hands-on teaching approaches. I get my thrill by planning activities for my children (6 yo girl & 3 yo boy) and watching them learn while having fun!
