SINCP(X)

• is any real number.

## Description

• This function shows the value of the cardinal normalized sin function.
• In  ,   is any real number.
• 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 normalized SINC function is called as SINCP and it 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

1. SINCP(23) = 8.814971340095828e-17
2. SINCP(-12) = -3.8981718325193755e-17
3. SINCP(45.3) = -0.0056847264326763776
