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 …

In mathematics, sine and cosine are trigonometric functions of an angle.

Jul 23, 2025 · Sine, cosine, and tangent are the primary trigonometric functions that relate the angles of a right triangle to the ratios of its sides. These functions are fundamental in …

Mar 7, 2025 · They are based on the six fundamental trigonometric functions: sine (sin), cosine (cos), tangent (tan), cosecant (cosec), secant (sec), and cotangent (cot). All the identities are …

This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides many practice problems on identifying the sides that are opposite and adjacent …

To calculate using sin, cos and tan, you need to know their trigonometric ratios (remember that the ratio of two values is a division of these values). Consider the right-angled triangle below.

Sin, cos, and tan are the basic trigonometric ratios in trigonometry, used to study the relationship between the angles and sides of a triangle (especially of a right-angled triangle).

Sine and cosine — a.k.a., sin (θ) and cos (θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin (θ) is the ratio of the opposite side to the …

Nov 14, 2025 · Sine and cosine are trigonometric functions that associate each angle, defined from the unit circle, with a value between -1 and +1.

Trigonometry Functions - Sin, Cos, Tan, Csc, Sec and Cot. Tangent, cotangent, secant, and cosecant of any angle. This tutorial covers the reciprocal identities and shows them in various …
