Trigonometry  Definition, Formulas, Ratios, & Identities
Trigonometry, the branch of mathematics concerned with specific functions of angles. There are six functions commonly used in trigonometry: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). Learn more about trigonometry in this article.
Sine, Cosine, Tangent  Math is Fun
Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a RightAngled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: "Opposite" is opposite to the angle θ "Adjacent" is adjacent (next to) to the angle θ "Hypotenuse" is the long one
