Trigonometric functions play a major role in geometric considerations as well as in the modelling of oscillations. We introduce these functions at the right-angled triangle and extend them periodically to ℝ using the unit circle. Furthermore, we will discuss the inverse functions of the trigonometric functions in this chapter. As an application we will consider the transformation between Cartesian and polar coordinates.
