comment What is the interval of definition of a solution of an ODE?
Oh so you could say $(-\infty, 1)$ or $(1, \infty)$ just not both?

comment What is the interval of definition of a solution of an ODE?
For $y(t)=1/(t-1)$ why wouldn't the interval be $(-\infty,1)\cup (1,\infty)$? Shouldn't it be anything that does not make the denominator 0?

@Cthulhu I think we have a misunderstanding, when I ask what it means, it doesn't help when reply "what do you think it should be"?

comment Continuity of piecewise function
What does $R^2 -> R$ mean? The pairs of real numbers being mapped to real numbers? That doesn't make sense.

@Rahul I think I first came across the term when reading about integer factorization algorithms. I found a mention of it here merriam-webster.com/dictionary/cyclic%20function

comment Why is $\sin(d\Phi) = d\Phi$ where $d\Phi$ is very small?
It is unknown whether you're asserting all trigonometric proof involve a degree of circular reasoning or if you are making a joke regarding how trigonometric functions are periodic.

@GeorgeV.Williams if you'd like to improve your answer you could explain why it makes sense to interpolate n! with another function.
