Using the definition of continuity directly prove that f: (0,infinity) -->R defined by
f (x) := 1/x is continuous.
I know you have to start with epislon>0 and finding a delta, but I can't come up with the right delta. Help?

instead you could use the other characterization of continuity.
you kno for x not equal to zero 1/x is exist in R.
now use algebraic limit theorem about reciprocal limits.
