A Brief Introduction to Trigonometry
Trigonometry forms a pivotal part of mathematics, especially when analyzing relationships within triangles. This article aims to shed light on the fundamental trigonometric functions: sine (sin), cosine (cos), and tangent (tan).
Understanding the Basics: The Right Triangle
To comprehend trigonometric functions, we start with a right triangle. Labeling the angles, we often denote a specific angle with the Greek letter Theta (θ). The sides of the triangle are defined as follows:
Opposite (op): The side opposite the angle θ.
Adjacent (a): The side adjacent to the angle θ.
Hypotenuse (H): The longest side of the triangle, opposite the right angle.
