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.


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


The two main branches of trigonometry are plane trigonometry and spherical geometry. Trigonometry in general deals with the study of the relationships involving the lengths of angles and triangles.


"Plane trigonometry" is a branch of mathematics that focuses on the relationship between the sides and angles of a triangle. Plane trigonometry builds upon the basic concepts of Euclidean geometry, and it has applications in a variety of mathematical fields, from physics to advanced calculus.


One of the most common applications of trigonometry in everyday life is the use of triangulation to determine the height of buildings, mountains, trees and other very tall or distant objects. Similar trigonometric functions are used to measure distances between points, such as between an ocean-bound


Successfully working through trigonometry problems requires knowledge of the properties of triangles as well as the ability to measure and understand the ratios called sine, cosine and tangent. Using equations associated with the ratios, it is possible to find the angles and lengths of right angle t


Trigonometry developed in many parts of the world over thousands of years, but the mathematicians who are most credited with its discovery are Hipparchus, Menelaus and Ptolemy. Isaac Newton and Euler contributed developments to bring trigonometry into the modern age.


To work as an architect, first earn a bachelor's degree in architecture, and then complete a three-year internship with an established architectural or design firm or with a licensed architect. Pass the Architect Registration Exam to earn a state license before working directly with clients.


According to the Bureau of Labor Statistics, architects made a median wage of $73,090 per year, or $35.14 per hour, as of May 2012. The top 10 percent of architects made more than $118,230, while the bottom 10 percent made less than $44,600.


Architects use math in several areas of design and construction, from planning the blueprints or initial sketch design to calculating potential structural problems that a site may encounter. Architects employ geometry, for example, when they use the Pythagorean theorem to calculate the size and shap
