Sinuksen
Sinuksen refers to the mathematical sine function, commonly written sin(x). It assigns to an angle the ratio of the opposite side to the hypotenuse in a right triangle and, more generally, can be defined on the unit circle as the y-coordinate of the point reached by rotating (1,0) by x radians from the positive x-axis.
Key properties of the sine function include its 2π periodicity, sin(x + 2π) = sin(x), and its odd
Sinus is closely related to other trigonometric functions such as cosine, with the Pythagorean identity sin^2(x) +
In Finnish, the sine function is called sinus, and sinuksen is the genitive form meaning “of the
