WebThe six trigonometric ratios of a right angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. They stand for Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent respectively. In the … WebThe graphs of these trigonometric functions also give us a clue as to which derivative contains the negative sign. At x = 0, sin(x) is increasing, and cos(x) is positive, so it makes sense that the derivative is +cos(x). On the other hand, just after x = 0, cos(x) is decreasing, and sin(x) is positive, so the derivative must be −sin(x).

There are several equivalent ways for defining trigonometric functions, and the proof of the trigonometric identities between them depend on the chosen definition. The oldest and somehow the most elementary definition is based on the geometry of right triangles. The proofs given in this article use this definition, and thus apply to non-negative angles not greater than a right angle. For greater and negative angles, see Trigonometric functions.
