Description

The Sin function calculates the cardinal sine ( unnormalized sinc function).

The cardinal sine is an analytical function. The standard is not defined uniformly, especially in English-speaking countries, sinc is used for both the normalized as well as the unnormalized variant is used.

Here and in the RedCrab Calculator the unnormalized version is implemented as shown in the following figure:

Kardinalsinus

In information theory and digital signal processing, the normalized form is mostly used:

Spaltfunktion


Input

The argument is given as a real number in degrees (-180 ° .. + 180 °) or radians (-π .. + π). The unit of measure used is set to degrees or radians in the pull-down menu.

Result

Sinc returns a result in the range from 0 to 1.
