Cos pi/2

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/2 pi, the angle pi lies on the negative x-axis.

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. These unwanted results do not come from function evaluations. It is because pi value cannot be represented in floating-point number. One approach to go around it is to use symbolic toolbox: sin sym pi returns 0.
