Trigonometric functions extend beyond acute angles to cover any angle in the unit circle. These functions, including sine, cosine, and tangent, represent ratios between sides of a right triangle formed by the angle and the unit circle's radius. By defining trigonometric functions for any angle, trigonometry becomes applicable across various contexts, aiding in navigation, physics, and engineering. Through periodicity and symmetries, trigonometric functions repeat their values, facilitating analysis of periodic phenomena. Additionally, advanced concepts like radians and the unit circle provide precise tools for understanding trigonometric functions in their broader domain, enabling accurate calculations and interpretations across disciplines. • More Lessons: http://www.MathAndScience.com • Twitter: / jasongibsonmath
