8. I was trying to evaluate a sum over a piecewise function, not unlike this example. However, my piecewise function needed to be defined differently for even and odd k. This is a simpler version of my function, just so we can all agree that the sum exists: f [k_]:=Piecewise [ { {1, k==0}, {x^k/k!, OddQ [k]}, {x^k/k!, EvenQ [k]}}] (I keep x and ...1. As far as I can remember, making visible gaps was introduced as a feature. Before that, piecewise or discontinuous functions were plotted like this: Plot [Piecewise [ { {x, x <= 1}, {3, x > 1}}], {x, 0, 3}, Exclusions -> None] That behavior gives the wrong impression. I would have to check when this was default or if I'm completely off here.A piecewise function is a function that is defined on a sequence of intervals. A common example is the absolute value, |x|={-x for x<0; 0 for x=0; x for x>0. (1) Piecewise functions are implemented in the Wolfram Language as Piecewise[{{val1, cond1}, {val2, cond2}, ...}].Find and classify the discontinuities of a piecewise function: The function is not defined at zero so it cannot be continuous there: The function tends to Infinity (on both sides), so this is an infinite discontinuity:
