# TRIGONOMETRY UNIT TEST

Trigonometry - Wikipedia
Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest
Trigonometry - dummies
Trigonometry is the study of triangles, which contain angles, of course. Get to know some special rules for angles and various other important functions, definitions, and translations. Sines and cosines are two trig functions that factor heavily into any study of trigonometry; they have their own formulas and rules that you’ll want to understand if you plan to study trig..
Understanding the unit circle | StudyPug
In the world of calculus, pre-calculus, and trigonometry, you will often find reference toward and problems regarding "the unit circle." But, oddly, we are rarely ever taught what it is! In simple terms, the unit circle is a mathematical tool for making the use of angles and trigonometric functions easier.
Free Trigonometry Questions and Problems
Free tutorials and problems on solving trigonometric equations, trigonometric identities and formulas can also be found. Java applets are used to explore, interactively, important topics in trigonometry such as graphs of the 6 trigonometric functions, inverse trigonometric functions, unit circle, angle and sine law.
