The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a right-angled triangle divided by another. For any angle "θ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.)

We define the cosine, sine and tangent as functions of all real numbers. These trigonometric functions are extremely important in science, engineering and mathematics, and some familiarity with them will be assumed in most first year university mathematics courses.

In this article, we are going to learn the basics of trigonometry such as trigonometry functions, ratios, trigonometry table, formulas and many solved examples. What is Trigonometry? Trigonometry is one of the most important branches in mathematics that …

This Trigonometry Handbook was developed primarily through work with a number of High School and College Trigonometry classes. In addition, a number of more advanced topics have been added to the handbook to whet the student’s appetite for higher level study.

Trigonometry is the study of triangles and their measurements (like side length, area, etc.) Specifically, we'll be discussing the measurements of right triangles. Now that we know what trigonometry is, let's start learning some of these measurements! Every angle of a right triangle has six measurements called trigonometric functions.

Learn about trigonometry, and its relationship to triangles, especially right angled triangles. Find out about the basic functions of sine, cosine and tangent.

What are the Basics of Trigonometry? Trigonometry basics deal with the measurement of angles and problems related to angles. There are six basic trigonometric ratios: sine, cosine, tangent, cosecant, secant and cotangent. All the important concepts covered under trigonometry are based on these trigonometric ratios or functions.

Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: Opposite is always opposite the angle. And Adjacent is always next to the angle.

De nition: Let x and y be given as described above. Then. give the de nitions of the cosine and sine functions, respectively. The following reference unit circle1 can help you with the values of cosine and sine for a range of common angles.
