So I had a pre calculus student ask me why the lim x->inf (1+1/x)^x is e. I
can prove it, but I've never noticed until he showed me this that in the
calculator, the graph of (1+1/x)^x actually goes to one when you plug
EXTREMELY large numbers into the table values. Does anyone know how to
explain this?
Greatly appreciate your thoughts!
