The Basics of Trigonometry

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. It finds widespread use in fields such as engineering, physics, and navigation. At the heart of trigonometry lies the tangent function.

Defining the Tangent Function

The tangent of an angle in a right triangle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to it. It is commonly abbreviated as \( \tan \). Mathematically, it is represented as:

\[ \tan(\theta) = \frac{{\text{Opposite Side}}}{{\text{Adjacent Side}}} \]
