What is trigonometry & unit circle dynamics?

Trigonometry extends right-triangle geometry to continuous periodic functions on the Cartesian plane via the Unit Circle (x² + y² = 1). For any angle θ measured counterclockwise from the positive x-axis, the coordinates of the terminal point on the circle are x = cos θ and y = sin θ, while the tangent is the slope of the radial line (tan θ = sin θ / cos θ). Projecting y(θ) continuously onto a moving time axis unfolds the fundamental sinusoidal wave.

Frequently Asked Questions

Trigonometry & Unit Circle Dynamics FAQ

2 Answers

On a unit circle of radius r = 1, any angle θ defines a right triangle with adjacent side x = cos θ, opposite side y = sin θ, and hypotenuse r = 1. Applying the Pythagorean theorem (a² + b² = c²) gives (cos θ)² + (sin θ)² = 1².
