There we are using its definition or an approximation of its value.  If you
plug e^(Pi*i) into google, you get 1 but that is because the limited
precision that computers use to represent floating point numbers gets
rounded.  For proof, try entering into google:
e^(Pi*i+1E-9)

The function Sine and the number e are both defined by an infinite series,
which have likewise never been physically realized.  You can either dispense
with the infinities, or dispense with the idea that math is man-made.

A circle's definition involves an infinite number of points having the same
distance from a center.  There has never been a physical construction or
representation of a circle.

The two senses I have seen you have articulate are the one in which
existence implies you can interact with something (your chair), and the
sense in which you cannot interact with it (numbers, past, beyond horizon,
etc.).  This view of existence seems rather egocentric; I don't see how the
existence or non existence of something can depend on one person's point of
view.  There are billions of people on this planet I will never meet, see,
or know, but I should not consider their existence to be a different sense
of the word.

So is it fair to say you believe there are an infinite number of primes?

"You can know the name of a bird in all the languages of the world, but when
you're finished, you'll know absolutely nothing whatever about the bird...
So let's look at the bird and see what it's doing — that's what counts. *I
learned very early the difference between knowing the name of something and
knowing something.*" -- Richard Feynmann

We might know the name "17" or the name "Pi", but we should not let these
simple labels fool us into thinking we know everything there is to know
