Trigonometric functions, commonly known as trig functions, are mathematical functions that relate the angles of a triangle to the ratios of its sides. They are fundamental in various branches of mathematics, physics, engineering, and computer science. The primary trig functions include sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These functions are used to analyze wave patterns, oscillations, and angular relationships in multiple scientific applications.
