Video 5 Introduction to Trigonometry
Hi! I'm Pritish Today, we will be talking about Trigonometry. This is the first video on Trigonometry. I would like to start with "Why do we want to study Trigonometry?" and "What is Trigonometry?" You would certainly know that Euclidean geometry is very fundamental to how we think about nature. The way we visualize things in Physics, for example, we use Euclidean geometry in the way we think. And often, Euclidean geometry requires some amount of innovative thinking to reason about problems. And often when you want to talk about Physics, you don't want geometry to be your bottleneck in thinking about Physics. So Trigonometry and Coordinate Geometry are two subjects which try to make a more systematic study of Geometry. And what is "Trigonometry"? Trigonometry is about a study of angles in an "algebraic" way. You would feel more comfortable doing Algebra Algebra is something you can do in a more mechanical way. Whereas, Geome...
