Radian Measure and Circular Functions

The Radian Measure presents an alternate method to degrees for calculating angles, and it's described as the proportion of the length of an arc to the radius. Circular functions, including sine and cosine, symbolize coordinates on a unit circle. These functions establish an essential link between geometry and analysis, playing a crucial role in several domains of mathematics and physics.
