Cos pi/2

The value of cos pi is

The cos trigonometric function calculates the cos of an angle in radians, degrees or gradians. Cosine function The calculator allows to use most of the trigonometric functions , it is possible to calculate the cosine , the sine and the tangent of an angle through the functions of the same name.. The trigonometric function cosine noted cos , allows to calculate the cosine of an angle online , it is possible to use different angular units : degrees, gradians and radians wich is the angular unit by default. The cosine calculator allows through the cos function to calculate online the cosine of an angle in radians, you must first select the desired unit by clicking on the options button calculation module. After that, you can start your calculations.

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. Note that sym pi is the exact pi. You had better use degrees rather than radians when your application needs to use correct values around such angles. Note that sind returns '0'. This would be a trick for handling 'pi' as if it is a real 'pi'. Converting radians to degrees makes the exact result around pi. These files are very short sample codes for understanding.
