In mathematics, sine and cosine are trigonometric functions of an angle.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 ...
In the article, Kort offered this definition: "Sides prefer to kiss, hug and engage in oral sex, rimming, mutual masturbation and rubbing up and down on each other, to name just a few of the sexual activities they enjoy. These men enjoy practically every sexual practice aside from anal penetration of any kind."

Metaphysics is the study of the most general features of reality, including existence, objects and their properties, possibility and necessity, space and time, change, causation, and the relation between matter and mind.
Even for quite large values of n, the actual distribution of the mean is significantly nonnormal. [21] Because of this problem several methods to estimate confidence intervals have been proposed. In the equations for confidence intervals below, the variables have the following meaning: n 1 is the number of successes out of n, the total number ...
The original composition date or century for the Kamasutra is unknown. Historians have variously placed it between 400 BCE and 300 CE. [16] [note 1] According to John Keay, the Kama Sutra is a compendium that was collected into its present form in the 2nd century CE. [17]
In mathematics, hyperbolic functions are analogues of the ordinary trigonometric functions, but defined using the hyperbola rather than the circle.Just as the points (cos t, sin t) form a circle with a unit radius, the points (cosh t, sinh t) form the right half of the unit hyperbola.
