# Algebra vs. Trigonometry: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 30, 2024

**Algebra involves mathematical operations with numbers and symbols, while trigonometry focuses on the relationships between angles and sides of triangles.**

## Key Differences

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols; it is about generalizing arithmetic. Trigonometry, on the other hand, is the study of triangles, focusing on the relationships between their angles and sides.

Algebra uses variables to represent numbers in equations and formulas, facilitating the solving of mathematical problems. In contrast, trigonometry uses functions like sine, cosine, and tangent to explore the properties of triangles.

The applications of algebra are broad and varied, including solving equations and finding unknowns. Trigonometry has specific applications, such as in navigation, engineering, and physics, particularly where angles and distances are involved.

Algebra forms the basis for advanced mathematics and is essential for studies in engineering, science, economics, and more. Trigonometry, while also crucial in many fields, is particularly fundamental in fields involving wave motion, periodic phenomena, and circular motion.

In algebra, the focus is often on abstract problem solving and logical reasoning. Trigonometry, however, often requires spatial visualization and understanding of geometric concepts.

#### Algebra

A branch of mathematics in which symbols, usually letters of the alphabet, represent numbers or members of a specified set and are used to represent quantities and to express general relationships that hold for all members of the set.

#### Trigonometry

The branch of mathematics that deals with the relationships between the sides and the angles of triangles and the calculations based on them, particularly the trigonometric functions.

#### Algebra

A set together with a pair of binary operations defined on the set. Usually, the set and the operations simultaneously form both a ring and a module.

#### Trigonometry

The branch of mathematics that deals with the relationships between the sides and angles of (in particular) right-angled triangles, as represented by the trigonometric functions, and with calculations based on said relationships.

Trigonometry emerged in the Hellenistic world during the 3rd century BCE from applications of geometry to astronomy; the Greeks focused on the calculation of chords, while mathematicians in India created the earliest known tables of values for trigonometric functions such as sine.

Historically, trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics and navigation.
