What is this session about
Vector algebra made interesting
Concepts from vector algebra are introduced at the higher secondary level. If we show students how it helps answer some interesting questions from diverse fields, they will find it more interesting.
Vector algebra can lead us to short and elegant proofs/solutions, when used in conjunction with ideas like symmetry
What do we discuss in this session?
Here we look the applications of vector algebra to answer some questions from trigonometry, geometry, chemistry and astronomy.
- Applying vector algebra to derive some trigonometric results in a simple manner
- An everyday example of finding the angle between pipes on perpendicular faces of a building
- The structure of a molecule like methane, using symmetry arguments
- Addressing misconceptions about phases of the Moon using a more involved application of vector algebra
