[?]Define sinc[x_]:=Piecewise[{{Sin[Pi x]/(Pi x), {x != 0}},{1, {x == 0}}}]

Posted 8 years ago

Hello everyone. I tried to define the following function: sinc[x_]:=Piecewise[{{Sin[Pi x]/(Pi x), {x != 0}}, {1, {x == 0}}}] but, when I plot it, the figure is empty. Why and how can I fix this problem? Plot[sinc[x], {x, -5, 5}] Thank you for your time.
