While this is technically only true for x ≠ 0, an interesting thing about this example is that its discontinuity and lack of differentiability at x = 0 can be "removed". Let f (x) = sin(x) x. Use your calculator to graph this over some window near x = 0.

The zero crossings of the unnormalized sinc are at non-zero integer multiples of π, while zero crossings of the normalized sinc occur at non-zero integers. The local maxima and minima of the unnormalized sinc correspond to its intersections with the cosine function. That is, sin(ξ)/ξ = cos(ξ) for all points ξ where the derivative of sin(x)/x is zero and thus a local extremum is reached. … WebJul 6, 2010 · Derivatives of the Sinc Function; Bernard Widrow, Stanford University, California, István Kollár, Budapest University of Technology and Economics; Book: … c\u0026a online shop belgië herenWeb1 Answer Sorted by: 6 Use the Taylor series expansion as mentioned in the comments to get: sinc ( x) = sin x x = − ∑ k = 0 ∞ ( − x) 2 k + 1 ( 2 k + 1)! x = − ∑ k = 0 ∞ ( − 1) 2 k + 1 … easley hotels sc
