The concept of Trigonometry came about during the third century BC and it usesapplications that stem from geometry.

This mathematical branch is the study of the relationshipsthat involve angles or triangles and lengths. Trigonometry includes sub categories such astrigonometric equations and identities and graphs of trigonometric functions, and ways to solveunknown sides of right and equilateral triangles. Trigonometry branches off onto six functions ofvery commonly used functions such as sine(sin), cosine(cos), tangent(tan), cotangent(cot),secant(sec), and cosecant (csc). These trigonometric functions are originally developed in orderto compute specific distances or angles in certain fields to solve problems.Trigonometry roots from the Greek word “trigonon” which means triangle, and metron,meaning “to measure”. Trigonometry received contributions from three Greek mathematicianslike Hipparchus, Menelaus, and Ptolemy. Historians have found that Hipparchus has been thefirst person to study trigonometry in 98 AD in Rome and he may also have been the one toinvent it because he is the only one to leave behind documentary evidence that allows them to tiehim to this math invention. Hipparchus was the first Greek to create a table that lists values fortrigonometric functions.

In the past, Trigonometry was used in Ancient Egypt for projects that requiredconstruction for projects like pyramid building. They were able to use the “run to rise” conceptof trigonometry in order to build their spherical shaped pyramid. As known in the Trigonometrysubject, there are differences between a spherical triangle and a general planar triangle.

In theEgyptians’ case, their pyramid is considered spherical triangles because their angles are equallyshaped, otherwise called congruency, which means identical in relation to both its size andshape, equipped with an angle that is always greater than 180 degrees. If the Egyptian pyramidwas built as a planar triangle, this would mean that their sides are similar, which refers to only itsshape, giving this shape an angle that always sum up to exactly 180 degrees. Trigonometry wasalso responsible in relation to science applications after it shifted from the original triangleconcept. By the 18 th and 19 th century, this subject helped event instruments, clocks, andnavigational tools that all depended on the formulas and concepts of this math invention.Today, Trigonometry has shifted from the past to our current the present. Trigonometryhas provided contributions towards engineering, architecture, manufacturing, and more sciences.Trigonometry is a part of my present because it is the basic concept of the buildings I walk ineveryday, it plays a huge role in the house that I have been raised in all of my life, and mostimportantly, it is a major part of producing tools, machines, and other processes for creating themerchandise I buy and use on a daily basis.

I believe that with taking this course, I definitely have a better understanding andadvantage of my immediate environment because Trigonometry is a subject that is responsibleand plays a part behind a lot of real world inventions that I never knew of in this day and time. Ifeel like understanding Trigonometry allows myself to understand certain concepts behind thestructures of buildings, and productions for simple things such as automobiles or those creativecutting scissors that make zigzag patterns.Trigonometry is a very important matter because it’s a part of everyday life. This mathsubject is the answer behind building cars and houses and without Trigonometry, there would beno way for us to travel back and forth to work or put a roof over our heads. I predict that in thefuture, Trigonometry will be responsible for providing better medicine and technology.

Thisamazing subject will allow us to create dynamic environments that’ll aim towards livinghealthier lives and create advanced systems that were once done manually, but will now be ableto be completed using high tech mechanisms to make tasks easier.
