Vor 3 Tagen · The trigonometric function are periodic functions, and their primitive period is 2 π for the sine and the cosine, and π for the tangent, which is increasing in each open interval (π /2 + k π, π /2 + (k + 1) π).
Vor 2 Tagen · Pythagorean identities. Trigonometric functions and their reciprocals on the unit circle. All of the right-angled triangles are similar, i.e. the ratios between their corresponding sides are the same. For sin, cos and tan the unit-length radius forms the hypotenuse of the triangle that defines them.

29. Juni 2024 · 1. Den Quotienten aus Gegenkathete : Hypotenuse nennt man den SINUS eines Winkels (sin α). 2. Den Quotienten aus Ankathete : Hypotenuse nennt man den COSINUS eines Winkels (cos α). 3. Den Quotienten aus Gegenkathete : Ankathete nennt man den TANGENS eines Winkels (tan α).
17. Juni 2024 · Learn about trigonometry, the branch of mathematics that deals with angles and their functions. Find out the history, formulas, and applications of sine, cosine, and tangent functions in plane and spherical trigonometry.
Vor 3 Tagen · 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 ...
