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 applications.

## Key Takeaways

- Algebra focuses on solving equations and finding unknown values using variables, while trigonometry deals with the relationships between angles and side lengths of triangles.
- Algebra is a fundamental branch of mathematics, whereas trigonometry is a sub-branch of geometry.
- Algebra applies in various fields like physics, engineering, and economics, while trigonometry is crucial for astronomy, navigation, and architecture.

## Algebra vs Trigonometry

Algebra is the branch of mathematics that teaches sets, commutative properties, and associative properties, including numbers, points, etc., while Trigonometry is the branch of mathematics that uses sine, cosine, and tangent to solve equations. Algebra has five types, and Trigonometry has two types.

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 a combination of variables and constants.

Trigonometry was invented in the 13th century. It involves various functions to find out angles and side relationships 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 โAl-jabrโ, 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, medicine, engineering, economics and many other related fields.

Al-Khwarizmi is known as the father of algebra and referred to Algebra as โThe science of restoring and balancingโ. A mathematician with expertise and thorough research in Algebra is often called an algebraist.

Algebra is a vast subject, has elementary algebra, linear algebra, abstract algebra, universal algebra, and 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 โxโ and โyโ, 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, and tangent, while the reciprocals of these functions are cosecant, secant and cotangent.

These functions have been tabulated to make solving easier. The word trigonometry has been derived from two Greek words, โTrigononโ, meaning triangle and โmetronโ, meaning to measure.

Historically, Trigonometry was a part of geometry and was declared 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, which covers angles and distances in one plane and spherical trigonometry, which covers angles and distances in three-dimensional space.

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

Trigonometry has real-life applications 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 the 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

- 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.
- Algebra uses polynomial equations of constants and variables of โxโ and โyโ to find a solution, while trigonometry uses the sine, cosine and tangent functions to achieve a solution.
- Al-Khwarizmi is considered the father of Algebra, while Hipparachus of Nicaea is considered the father of Trigonometry.
- Algebra is derived from the Arabic word โAl-jabr โ, which means reunion of broken parts, while trigonometry is derived from two Greek words โTrigononโ and โmetronโ, which means triangle and to measure, respectively.
- 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.
