Beziehung zwischen Sinus, Kosinus und Tangens YouTube
The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse ), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse.

Trigonometry is a branch of mathematics. The word itself comes from the Greek trigōnon (which means "triangle") and metron ("measure"). As the name suggests, trigonometry deals primarily with angles and triangles; in particular, it defines and uses the relationships and ratios between angles and sides in triangles.The primary application is thus solving triangles, precisely right triangles.

A sinus is a sac or cavity in any organ or tissue, or an abnormal cavity or passage caused by the destruction of tissue. In common usage, "sinus" usually refers to the paranasal sinuses, which are air cavities in the cranial bones, especially those near the nose and connecting to it.

t. e. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities, which are.

For example, we define the two major circular functions, the cosine and sine in terms of the unit circle as follows. Figure 1.2.1 1.2. 1 shows an arc of length t t on the unit circle. This arc begins at the point (1, 0) ( 1, 0) and ends at its terminal point P(t) P ( t). We then define the cosine and sine of the arc t t as the x x and y y.

Hodnota sinus je také záporná. Překlopili jsme se přes obě osy. Napíšeme si to. Máme sin (Θ plus π), což je to samé jako sin (π plus Θ), a to se rovná -sin (Θ). Vidíte, tady je sin (Θ), toto je sin (π plus Θ) nebo sin (Θ plus π), to je jedno. Dostaneme cos (Θ plus π). cos (Θ plus π) se bude rovnat -cos (Θ).

2 Answers. Sorted by: 1. Use e i x = cos ( x) + i sin ( x) and e − i x = cos ( x) − i sin ( x) to get cos ( x) = ( e i x + e − i x) / 2 and sin ( x) = ( e i x − e − i x) / ( 2 i). These hold for any complex x. Note that if x = u + i v where u and v are real then e x = e u + i v = e u e i v = e u ( cos ( v) + i sin ( v)) = e u cos ( v.
