Trigonometric functions, often referred to as trig functions, are mathematical functions that relate the angles of a right triangle to the ratios of the lengths of its sides. The six fundamental trigonometric functions are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). These functions are widely used to solve problems involving angles and distances in various fields of science and engineering.

## Understanding the f(π) Calculator

The f(π) calculator is a specialized trigonometric calculator that allows you to evaluate trigonometric functions at specific angles measured in radians, where π (pi) is a significant constant representing the ratio of the circumference of a circle to its diameter. This calculator simplifies the process of finding the values of trigonometric functions, making it a valuable tool for students, professionals, and anyone dealing with trigonometry.
