Some Applications of Trigonometry
Applications of Trigonometry
There is an enormous number of applications of trigonometry and trigonometric functions. Historically, it was developed for astronomy and geography, but scientists have been using it for centuries for other purposes, too. Fields which make use of trigonometry or trigonometric functions include acoustics, optics, statistics, medical imaging, chemistry, seismology, meteorology, land surveying, architecture, electrical engineering, mechanical engineering, civil engineering, computer graphics, etc. Since these fields are used throughout the natural and social sciences, trigonometry is a very useful subject to know.
GEOLOGY
Geologists apply trigonometry differently according to their specialized field.
Seismologists use trigonometry to accurately determine the epicenter of an earthquake.
Paleontologists use trigonometry to determine the actual width of geological bed in earth’s crust.
SOUND
Sound engineers who work in advancing computer music and hi tech composers have to apply the basic law of trigonometry such as the cosine and the sine functions.
Engineering and Physics
Engineers, both military engineers and otherwise, have used trigonometry nearly as long.
Physics lays heavy demands on trigonometry. Optics and statics are two early fields of physics that use trigonometry, but all branches of physics use trigonometry since trigonometry aids in understanding space.
Mathematics and its applications
Trigonometry is used throughout mathematics, and, since mathematics is applied throughout the natural and social sciences, trigonometry has many applications. Calculus, linear algebra, and statistics, in particular, use trigonometry and have many applications in the all the sciences.
Clinometer
An clinometer is an instrument for measuring angles of slope (or tilt), elevation or depression of an object with respect to gravity. It is also known as a tilt meter, tilt indicator, slope alert, slope gauge, gradient meter, etc. Clinometers measure both inclines (elevation) and declines (depression) using three different units of measure: degrees, percent, and topography.
