2018-02-11 18:51:42 +0100	asked a question	piecewise defined function via def I've made the following experiment with Sage: `def f(x): if (0<= x<= 1/2): return 1 else: return 0 assume(0<= x<= 1/2) show(f(x)) show(f(1/3))` However I get outputs 0 and 1 respectively. Can someone clarify please? Thanks.
