Cos pi /2

File Exchange. The pi in matlab is not a real 'pi', but it is only a floating-point number close to 'pi'. Trigonometric functions around pi may have errors close to machine precision.

The value of cos pi is In this article, we will discuss the methods to find the value of cos pi with examples. For cos pi, the angle pi lies on the negative x-axis. Using trigonometry formulas, we can represent the cos pi as:. Here, the value of sin pi is equal to 0. The value of cos pi is equal to the x-coordinate

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:.

You had better use degrees rather than radians when your application needs to use correct values around such angles. The cos of pi equals the x-coordinate -1 of the point of intersection -1, 0 of unit circle and r. There is a remedy for it! Maths Questions.
