Thankyou!

Usually it's a combination of:

1. Dumb luck at choosing the correct search string.

2. Sifting through the hits (which also means moving on to pages 2, 3 .....) until I find something I like.

Sometimes I'll have it saved as a favorite.

It's always nice to come across something new, interesting, different or comprehensive.

1)Continous functions on closed intervals are uniformly continous.
2)Let there is so that for all points in interval.
3)Let be partition with
4)Then (the difference of the upper and lower sums with respect to ) can be made sufficiently small.
