What are trigonometric ratios of any magnitude in degree and radians?
In this post, we learn to solve problems involving trigonometric ratios of angles of any magnitude in both degrees and radians, as a part of the Prelim Maths Advanced course under the topic Trigonometric Functions and sub-part Radians. As the unit circle’s domain ranges from 0^{o} to 360^{o} , or 0 to 2\pi radians, if the angle given is greater than the intial domain, it just keeps going clockwise around the unit circle. As a result of this, if the given angle is not between 0^{o} to 360^{o} , or 0 to 2\pi radians, we can add or subtract 360^{o} or 2\pi . The videos below explain it in further detail.
Introduction to trigonometric functions
The following two videos cover angles of any magnitude and how it is used in relation to trigonometric functions.
