According to
Infinity (Wikipedia)
x/∞ = 0 (where x is a real number) but 0·∞ is indeterminate (except in some contexts). It also states that [x/∞ = 0] is not equivalent to [0·∞=x].
So is there an error in this wiki, or is there disagreement, or is it coming from a different context?
And could one say x/∞ = dx? The infinite slice is infinitessimal?
