Trigonometry has applications in a number of scientific fields, ranging from geography and astronomy to engineering and physics. One of the most important early real-life examples of trigonometry involved using the knowledge that the earth was a sphere for navigation. Ptolemy put trigonometry to wor


Trigonometry is important to mathematics as an element of calculus, statistics and linear algebra. Outside of mathematics, it is important to physics, engineering, geography and astronomy as well as architectural design.


Trigonometry books compile the rules and uses of trigonometry, as well as graphs and practice problems. Many of these books are available for purchase or may be checked out from a library.


Trigonometry is used by engineers, medical services technicians, mathematicians, data entry specialists, loggers, statisticians, actuaries, drafters, chemists, economists, physicists, registered nurses, building inspectors, boilermakers, machinists and millwrights. Approximately 50 different jobs in


One application of trigonometry in the real world is determining the distance and location of faraway objects. This is useful in navigation and in surveying. Historically, trigonometry was also applied to determine the position of heavenly bodies, but this use has been supplanted by linear algebra i


Engineering is an extremely mathematics-intensive career, with necessary skills in both trigonometry and calculus to describe mechanical designs and to make aesthetic designs practical. The understanding of angles and planes is the most common skill used by engineers. Trigonometry also contains an u


A typical trigonometry problem is: If the bottom of a ladder leaning against a building is 15 feet from the base of the building and forms a 45-degree angle with the ground, how tall is the ladder? Another example involves a ramp that is 40 feet long and set at a 20-degree angle of inclination. How


Many historians refer to Hipparchus as the father of trigonometry, according to the New Mexico Museum of Space History. Hipparchus was born in about 190 B.C., and he spent most of his life in Rhodes, Greece.


Students can visit Khan Academy to find online tutorials on various trigonometric topics, such as unit circles, graphing trigonometric functions and trigonometric identities. Online calculators, such as the trigonometric equation calculator on Symbolab and the right triangle calculator on the Carbid


Trigonometry is often used in real world applications, such as astronomy, architecture, engineering, music theory and geography. Trigonometry was originally developed for geography and astronomy.
