Sin (θ), Tan (θ), and 1 are the heights to the line starting from the x -axis, while Cos (θ), 1, and Cot (θ) are lengths along the x -axis starting from the origin. If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other.

In this right triangle: sin A = a/h; cos A = b/h; tan A = a/b. Trigonometric ratios are the ratios between edges of a right triangle. These ratios depend only on one acute angle of the right triangle, since any two right triangles with the same acute angle are similar .
For sin, cos and tan the unit-length radius forms the hypotenuse of the triangle that defines them. The reciprocal identities arise as ratios of sides in the triangles where this unit line is no longer the hypotenuse.
All of the trigonometric functions of any angle can be constructed using a circle centered at O with radius of 1. Trigonometric functions: Sine, Cosine, Tangent, Cosecant, Secant, Cotangent. In mathematics, the trigonometric functions are a set of functions which relate angles to the sides of a right triangle.
Trigonometry (from the Greek trigonon = three angles and metron = measure) is a part of elementary mathematics dealing with angles, triangles and trigonometric functions such as sine (abbreviated sin), cosine (abbreviated cos) and tangent (abbreviated tan).
18 wrz 2024 · There are six trigonometric functions in Trigonometry: sine, cosine, tangent, cotangent, secant, and cosecant.
In trigonometry, the three ratios form the basis of definition of the three basic trigonometric functions, called the sine, cosine, and tangent. Given an acute angle \ ( \theta \), construct a right triangle one (or both) of whose acute angles is \ ( \theta \):
