# Difference Between Algebra and Trigonometry (With Table)

Mathematics is a vast subject. It offers four basic concepts that are addition, subtraction, multiplication, and division. But a deeper study involves familiarity with concepts like algebra, geometry, trigonometry, mensuration, and many more. The concepts can range from basic to advance and have real-world application.

## Algebra vs Trigonometry

The main difference between Algebra and Trigonometry is that Algebra involves equations, rules, and polynomials. The aim is to solve the mathematical equation of variables and constants. While Trigonometry involves angles of triangles and measurements of sides. The aim is to find the angles and sides with the use of sine, cosine, and tangent.

Algebra was introduced before trigonometry in the mathematical world. Algebra requires the manipulation of symbols. It simplifies huge word questions into simple equations and can be solved with various formulas. Algebra can be further classified into elementary algebra, linear algebra, abstract algebra, and algebraic geometry. Algebra is usually a combination of variables and constants.

Trigonometry was invented in the 13th century. It involves various functions to find out angles and side relationship with the triangles. It can be further classified into two types, planar and spherical trigonometry.

## What is Algebra?

Algebra is derived from the Arabic word “Al-jabr” meaning reunion of broken parts. Algebra integrates simple mathematical concepts like integers, natural numbers, whole numbers, factorials and basic properties like commutative, associative, distributive and identity of numbers. It forms the basis of domains like science, medicines, engineering, economics and many other related fields.

Al-Khwarizmi is known as the father of algebra and referred Algebra as “The science of restoring and balancing”. A mathematician with expertise and thorough research in Algebra is often called as an algebraist. Algebra being a vast subject has elementary algebra, linear algebra, abstract algebra, universal algebra, boolean algebra as the sub-parts. Algebra includes calculus, arithmetic, geometry and trigonometry to solve complex problems.

Elementary algebra includes the basics of algebra. The formulation of elementary algebra includes basic arithmetic operators and symbols. Abstract algebra involves sets, binary operations, polynomials, identity elements, inverse elements, associativity and commutativity.

Algebra is utilized functionally in solving various real life problems like medical diagnosis, decision making, statistical inferences, search engine optimization (SEO), graphics, facial recognition and widely in coding. Life may not have determined variables like “x” and “y”, but algebra is efficiently valid in different walks of life. Algebra provides adaptability and simplicity in most complex situations.

## What is Trigonometry?

Trigonometry is a concept in Mathematics which consists of angles and sides. The six major functions of angles used in trigonometry are sine, cosine, tangent, while the reciprocals of these functions are cosecant, secant and cotangent. These functions have been tabulated to make solving easier. The trigonometry word has been derived from two Greek words “Trigonon” meaning triangle and “metron” meaning to measure.

Historically, Trigonometry was a part of geometry and was declared as a separate subject after the 16th century. Hipparachus was the first mathematician to tabulate the values of trigonometric functions. Trigonometry can be classified into two types: plane trigonometry that covers angles and distances in one plane and spherical trigonometry that covers angles and distances in three-dimensional space.

There are various laws that govern the arbitrary triangle states like law of sines, law of cosines and law of tangents. Identities like Pythagorean identities, Euler’s formula, half-angle identities, the angle sum and difference identities are applied in the subject.

Trigonometry has real life application in fields like astronomy, navigation, artillery range evaluation, surveying, mapmaking, periodic functions, optics and acoustics, medical imaging, cryptology and many more. It was an essential subject during construction project of pyramids in Egypt. The heliocentric system of Nicolaus and the geocentric system of Ptolemy was based on Trigonometry.

## Main Differences Between Algebra and Trigonometry

1. Algebra is a concept of maths that deals with variables, constants, equations and rules while trigonometry is a concept of maths that deals with angles of triangles and measurements of sides.
2. Algebra uses polynomial equations of constants and variables of “x” and “y” for finding solution while trigonometry uses the sine, cosine and tangent functions to achieve solution.
3. Al-Khwarizmi is considered as the father of Algebra while Hipparachus of Nicaea is considered as the father of Trigonometry.
4. Algebra is derived from an Arabic word “Al-jabr “ which means reunion of broken parts while trigonometry is derived from two Greek word “Trigonon” and “metron”, which means triangle and to measure respectively.
5. Algebra is used in fields like decision making, SEO, graphics while trigonometry is used in fields like astronomy, navigation, optics, acoustics and many other domains.

## Conclusion

Algebra and trigonometry are intertwined subjects of mathematics and play an integral role in concept building. Algebra simplifies complex problems and trigonometry forms the basis of many scientific discoveries. Algebra deals with equations, variables and constants while trigonometry focuses on angles and relationship of sides of triangles.

Algebra and trigonometry are not just theoretical concepts but forms a basis in various real domains. Both the subjects are widely used during construction projects, cartography, cryptology, oceanography, naval and aviation industry, criminology, optics and acoustics, medical imaging and diagnosis, public surveying, website ranking, search engine optimization (SEO), search engine marketing (SEM), navigation and mapmaking, and various other architectural and engineering project.
