**SINC(X)**

- is any real number.

## Description

- This function shows the value of the cardinal sin function.
- In , is any real number.
- The full name of the function is sine cardinal,but it is commonly referred to by its abbreviation, Sinc.
- The unnormalized SINC function is defined by :

- The normalized SINC function is defined by .
- The value at x = 0 is defined to be the limiting value Sinc(0) = 1.
- The only difference between the two definitions is in the scaling of the independent variable (the x-axis) by a factor of π.

## Examples

- SINC(9) = 0.04579094280463962
- SINC(-34) = 0.015561255474118348
- SINC(-51.7) = 0.019163025320677915
