*This function shows the value of the cardinal sin function.

*This function shows the value of the cardinal normalized sin function.

*In <math>SINCP(X)</math>, <math>X</math> is any real number.

*In <math>SINCP(X)</math>, <math>X</math> is any real number.

*The full name of the function is sine cardinal,but it is commonly referred to by its abbreviation, Sinc.

*The full name of the function is normalized sine cardinal,but it is commonly referred to by its abbreviation, Sincp.

*The unnormalized SINC function is defined by :

*The unnormalized SINC function is defined by :

<math>SINC(X)=\begin{cases}

<math>SINC(X)=\begin{cases}

*The value at x = 0 is defined to be the limiting value Sinc(0) = 1.

*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.

*The only difference between the two definitions is in the scaling of the independent variable (the x-axis) by a factor of π.
