trigonometry - sinc function centered at x=c that goes to zero at x=0?

The sinc function is ordinarily defined as



sinc(x)=sinxx if x0 else 1.




I want a sinc function that is shifted away from the origin such that it's centered at some value c, and also equals zero at x=0. How can I define this function?
