Trigonometry is used in aviation extensively, both in the calculations performed by the machines and computers used by the pilots, and by pilots performing quick rudimentary calculations and estimates themselves. Trigonometry and trigonometric functions are used to estimate distances and landing patterns and navigate around obstacles.Continue Reading
Although the extent to which trigonometry is used by pilots and other navigators has dwindled over the years, many of their methods and computer systems are heavily ground in trigonometry and advanced mathematics. GPS, which can be found aboard nearly every modern air vehicle, uses the principles of trigonometry to compute distances and routes between locations.
Trigonometry allows pilots and flight engineers to account for their speed, velocity, angle of ascent or descent, as well as other external factors such as wind speed and direction. To do this, they utilize triangles and other structures composed of vectors. Computations involving these vectors allow them to solve complex problems and accurately model the behavior of their vehicles and environments.
Many pilots are also trained in the use of on-the-spot trigonometry to come up with quick estimates of their location and positioning in the air space. Usually, these calculations are based on the angle and position of the sun relative to a pilot's plane.Learn more about Trigonometry
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 work in his work "Geography", and Christopher Columbus used trigonometry in finding his way from Spain to what he thought was India but ended up being the New World.Full Answer >
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.Full Answer >
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 categories including management, farming, professional services, administration, construction, production and installation use trigonometry.Full Answer >
Trigonometry is used to measure the distance to stars in the solar system, and the motion of nearby stars compared to more distant stars. The method of measuring distance in space is called trigonometric parallax.Full Answer >
