| This piecewise function is not defined on the intervals (-oo,1) and [8,oo], but wolfram alpha is saying it has a domain of all Reals. Why is this? The plot even shows h(1/2) = 0. The function doesn't specify what happens at t=1/2, so how do... |
| Is it possible to make a plot of a cut of the rational line on wolfram alpha? e.g. $A=\{x\in\mathbb{Q}:x\leq0\vee x^2 0\wedge x^2\geq 2\}$ |
| found that you can also get more precision by keeping the decimal point and adding a bunch of zeros: ... |
