Circular Functions (sine, Cosine, Tangent)
overall review score: 4.8
⭐⭐⭐⭐⭐
score is between 0 and 5
Circular functions, including sine, cosine, and tangent, are fundamental trigonometric functions that relate angles of a right triangle to the ratios of its sides. They are widely used in mathematics, physics, engineering, and computer science to model periodic phenomena such as waves, oscillations, and rotations. These functions are defined on the unit circle, providing a continuous and periodic framework for analyzing angular relationships.
