The value of sin pi is 0. In this article, we will discuss the methods to find the value of sin pi with examples. For sin pi, the angle pi lies on the negative x-axis. Using trigonometry formulas, we can represent the sin pi as:. Sin pi is the value of sine trigonometric function for an angle equal to pi radians.

Sinpi 2

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 identities potentially involving angles but also involving side lengths or other lengths of a triangle. These identities are useful whenever expressions involving trigonometric functions need to be simplified. An important application is the integration of non-trigonometric functions: a common technique involves first using the substitution rule with a trigonometric function , and then simplifying the resulting integral with a trigonometric identity. The basic relationship between the sine and cosine is given by the Pythagorean identity:. This equation can be solved for either the sine or the cosine:. Using these identities, it is possible to express any trigonometric function in terms of any other up to a plus or minus sign :. By examining the unit circle, one can establish the following properties of the trigonometric functions. These are also known as reduction formulae.
