SINC(X)

This function shows the value of the cardinal sin function.
In $SINC(X)$ , $X$ 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 :

$SINC(X)={\begin{cases}1&forx=0\\{\frac {Sinx}{x}}&Otherwise\\\end{cases}}$

The normalized SINC function is defined by $SINC(X)={\frac {SIN\pi x}{\pi x}}$ .
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.
