Trigonometry can find that missing angle and distance. Questions like these are common in engineering, computer animation and more. And trigonometry gives the answers! 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 ":

Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') [1] is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.

The meaning of TRIG is trigonometry. How to use trig in a sentence.

This trig calculator finds the values of trig functions and solves right triangles using trigonometry.

It covers trigonometric ratios such as sine, cosine, and tangent. It explains how to evaluate it using right triangle trigonometry and SOHCAHTOA. In addition, it explains how to solve the...

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.

Trigonometric functions are functions related to an angle. There are six trigonometric functions: sine, cosine, tangent and their reciprocals cosecant, secant, and cotangent, respectively. Sine, cosine, and tangent are the most widely used trigonometric functions. Their reciprocals, though used, are less common in modern mathematics.

Check out two popular trigonometric laws with the law of sines calculator and our law of cosines calculator, which will help you to solve any kind of triangle. This trigonometry calculator has two sections that perform two different functions using trigonometry.
