What is Trigonometry?

An Intro Overview

These posts are for people who are highly preoccupied with educational issues.

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is based upon right triangles, where one angle is always 90 degrees. Trigonometry explores the trigonometric functions such as sine, cosine, tangent, cosecant, secant, and cotangent, which relate the angles of a triangle to the lengths of its sides.

Calculations are based upon the Cartesian Coordinate System using the familiar x and y axes within The Unit Circle.

The unit circle is a fundamental concept in trigonometry. It's a circle with a radius of 1 unit centered at the origin of a coordinate plane. In trigonometry, the unit circle is used to define the trigonometric functions of sine and cosine for all angles, including those beyond the range of 0 to 90 degrees.

Trig functions are used extensively in fields such as physics, engineering, astronomy, architecture, and more.

Trigonometry also extends beyond right triangles to include the study of periodic phenomena and the properties of waves. It's a fundamental tool in various mathematical and scientific disciplines.
